Description
Technical Field
The invention relates to the technical field of modulation, in particular to a method and a device for loading modulation parameters, a processor and electronic equipment.
Background
Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) are two Modulation methods commonly used in the field of power electronics, and in order to make the current switching period completely execute, the Modulation signal generation module is usually configured in a SHADOW (SHADOW) mode, that is: when the modulation parameter changes, the modulation signal generation module needs to wait until a set loading point to LOAD (LOAD) a new parameter so as to generate a new modulation signal. Under normal conditions, each modulation signal with the same and unique loading point updates parameters at the unique loading point in the same period; however, for a serial processor such as a DSP, the program execution is sequential, and the modulation signal generation module that updates the parameter later may lag behind the modulation signal generation module that updates the parameter earlier by one cycle or more before loading the new modulation parameter, thereby causing the overall output of the system to deviate from expectations.
As shown in fig. 1a and fig. 1b, taking PWM modulation and PFM modulation as examples, respectively, when the actual load points of two paths of modulation signal generation modules with the same set load point and the same unique modulation signal generation module differ by one period, the generated modulation signal synthesis result is shown as a waveform in a dashed line box in fig. 1a, and due to the inconsistency of load points in PWM modulation, there is an abnormal synthesis output in the switching transition process; as shown by the waveforms in the dashed box of fig. 1b, there is an anomaly in the synthesized output consistently not matching the expectation since the switching transition process was started at the time of PFM modulation due to load point inconsistency.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.

First, in order to facilitate understanding of the embodiments of the present invention, some terms or nouns referred to in the present invention will be explained below:
modulation signal: in the process of converting the electrical signal, the a signal changes some characteristic values (such as phase, frequency, amplitude, etc.) of the B signal, which causes these characteristic values of the B signal to change regularly, and the rule is determined by the rule of the a signal itself, i.e. the B signal carries the relevant information of the a signal, then the a signal is a modulated signal, and the B signal is a modulated signal.
A modulation signal generation module: is a module for generating a modulated signal, typically comprising a counting module and a comparing module, which updates the modulated signal output when the value of the counting module (count value) matches the value of the comparing module (i.e. comparison value). The counting module may have different counting manners, for example, including count up, count down, count up and count down, etc. as shown in fig. 2, the maximum value counted by the counting module is generally defined as a period value, and the minimum value is defined as a zero point.
Shadow mode: after the modulation parameters are updated, the modulation parameters are loaded until the set loading point, and the modulation parameters are loaded immediately corresponding to the set loading point; the shadow mode is that after the modulation parameters of each modulation signal are updated, new modulation parameters are loaded until a set loading point, and typical loading points comprise a zero point, a comparison value point and a period value point.
Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for loading modulation parameters, it is noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that illustrated herein.
Fig. 3 is a flowchart of a method for loading modulation parameters according to an embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:
step S102, determining modulation parameters to be updated and preset loading time of all modulation signals output by a controller, wherein the modulation parameters to be updated are the modulation parameters to be updated of all the modulation signals, and the preset loading time is preset loading time for loading the modulation parameters to be updated;
step S104, dividing all the modulation signals into a first type modulation signal and a second type modulation signal according to the preset loading time, wherein the first type modulation signal is a modulation signal with the same preset loading time, and the second type modulation signal is a modulation signal with different preset loading times;
step S106, controlling the first type modulation signal and the second type modulation signal to respectively execute a loading operation, where the loading operation is used to load the modulation parameter to be updated.
In the embodiment of the invention, modulation parameters to be updated and preset loading time of all modulation signals output by a controller are determined, wherein the modulation parameters to be updated are the modulation parameters to be updated of all the modulation signals, and the preset loading time is the preset loading time for loading the modulation parameters to be updated; dividing all the modulation signals into a first type of modulation signals and a second type of modulation signals according to the preset loading time, wherein the first type of modulation signals are modulation signals with the same preset loading time, and the second type of modulation signals are modulation signals with different preset loading times; and controlling the first type modulation signal and the second type modulation signal to respectively execute loading operation, wherein the loading operation is used for loading the modulation parameter to be updated, so that the aim of avoiding the error of updating the modulation parameter in the execution process of the switching period is fulfilled, the technical effect of ensuring that the output result of the switching period is in accordance with the expectation is realized, and the technical problem that the output result is deviated from the expectation due to the deviation of the time sequence of the updated modulation parameter in the execution process of the switching period in the prior art is solved.
Optionally, the loading method of the modulation parameter may be applied, but not limited to, in the field of power electronic modulation technology, for example, pulse width modulation FWM and pulse frequency modulation PFM, where during PWM modulation, the switching frequency of the power electronic device is fixed and the ratio of the conducting time in the switching period varies according to the control requirement; during PFM modulation, the switching frequency of the power electronic device is changed according to the control requirement, and the conducting time ratio in the switching period is fixed.
Optionally, the modulation parameters to be updated are modulation parameters to be updated of all the modulation signals, and the preset loading time is a preset loading time for loading the modulation parameters to be updated. The first type of modulation signals are modulation signals with the same preset loading time, and the second type of modulation signals are modulation signals with different preset loading times.
It should be noted that, when the two modulation schemes are implemented by using a digital controller such as a DSP, the PWM modulation scheme and the PFM modulation scheme respectively correspond to changes of a comparison Value (CMP) and a Period Value (PRD) of a modulation signal, and the comparison Value and the Period Value are collectively referred to as a modulation parameter (for example, a modulation parameter to be updated) in the embodiment of the present application.
The modulation parameter loading method provided by the embodiment of the application can be applied to more and more complex application scenes due to the fact that abnormal output types caused by inconsistent loading points are increased along with the increase of the number of modulation signal paths, and the modulation parameter updating position of the modulation signals is limited, so that the modulation signals with the same set loading points all load the modulation parameters at the set loading points in the same period, and therefore adverse effects on system output or system performance are avoided.
For convenience of description, the time when the modulation parameter to be updated is given to each modulation signal is referred to as modulation parameter update time, and the time when the update operation is completed is referred to as update completion time.
It should be noted that, unlike the modulation parameter loading point, the modulation parameters of the respective modulation signals are limited by the sequence of program execution and are difficult to update at the same time. Through the shadow mode, all modulation signals with the same set loading point in one controller module can load modulation parameters at the same loading point.
In an optional embodiment, dividing all the modulation signals into a first type modulation signal and a second type modulation signal according to the preset loading time includes:
step S202, determining the preset loading time of each path of modulation signal in all the modulation signals in a modulation period;
step S204, comparing whether the preset loading moments of all the modulation signals are the same or not;
step S206, dividing all the modulation signals into the first type modulation signals and the second type modulation signals according to the comparison result.
In the above optional embodiment, the preset loading time of all modulation signals is obtained by determining the preset loading time of each modulation signal in the modulation period, and the comparison result is obtained by comparing whether the preset loading times of all modulation signals are the same, so that the modulation signals with the same preset loading time at the preset loading time are divided into the first type of modulation signals, and the modulation signals with different preset loading times at the preset loading time are divided into the second type of modulation signals.
As an optional implementation manner, an implementation flow of another optional modulation parameter loading method is shown in fig. 4, and implementation steps are specifically described as follows:
step S601, acquiring the time required for completing the updating of the modulation parameters of all the modulation signals.
Specifically, assuming that a certain controller outputs 8 modulation signals, the 8 modulation signals sequentially update the modulation parameters, and the set loading points of the 8 modulation signals are the same, the time required from the start of updating the modulation parameter of the 1 st modulation signal to the end of updating the modulation parameter of the 8 th modulation signal needs to be estimated in advance.
Step S602, obtaining modulation parameters to be updated and preset loading time of all modulation signals.
In particular, the modulation parameters may be updated online according to the system control feedback signal.
Step S603, judging whether the time difference between the parameter updating time and the preset loading time is less than the time required by the completion of the parameter updating of the modulation signal, if so, skipping to step S604; if not, go to step S605.
Specifically, after the modulation parameter to be updated (the latest modulation parameter) is obtained, it is first determined whether a corresponding time difference between a time count value at which the 1 st-path modulation signal starts to be updated and a preset loading time count value is less than the time required for updating the 8-path modulation parameter, and if so, the process goes to step S604; if not, go to step S605.
Step S604, after waiting for the preset loading time, updating the modulation parameters for each modulation signal.
Specifically, after the count value exceeds the preset loading time, the modulation parameter of each modulation signal is updated to the latest modulation parameter.
In step S605, the modulation parameters are immediately updated for each modulated signal.
Specifically, the modulation parameter of each modulated signal is immediately updated to the latest modulation parameter.
In step S606, the modulation signals with the same loading point load the latest modulation parameters at the same loading point in the same cycle.
Specifically, after the modulation parameters of each modulation signal are updated to the latest modulation parameters, the modulation signals with the same load point will load the latest modulation parameters at the same load point in the same cycle. Unlike the prior art shown in fig. 1a and fig. 1b, under PWM modulation and PFM modulation, a possible synthesized output result is obtained when the actual load points of the two modulation signals shown in fig. 5a and fig. 5b are the same.
In an alternative embodiment, the controlling the first type of modulation signal to perform a loading operation includes:
step S302, obtaining the update completion time of each first type modulation signal, wherein the update completion time is the time for updating the modulation parameters to be updated;
step S304, judging whether the updating completion time and the preset loading time are in the same loading period;
step S306, if yes, the updating completion time and the preset loading time are compared in the current period to obtain a comparison result;
step S308, if the update completion time is before the preset loading time, immediately performing the update when receiving the modulation parameter to be updated, and performing the loading operation at the preset loading time.
Controlling the first type modulation signals to execute loading operation, namely acquiring the update completion time of each first type modulation signal, wherein the update completion time is the time for updating the modulation parameters to be updated; judging whether the updating completion time and the preset loading time are in the same loading period or not; if so, comparing the updating completion time with the preset loading time in the current period to obtain a comparison result; and if the updating completion time is before the preset loading time, immediately executing updating when the modulation parameters to be updated are received, and executing the loading operation at the preset loading time.
For the first type modulation signals with the same preset loading time, if the updating completion time of the first type modulation parameters spans the preset loading time, namely the updating completion time is behind the preset loading time, updating the modulation parameters to be updated after the preset loading time; and if the updating completion time of the first type modulation parameters is completed before the preset loading time, immediately updating when the modulation parameters to be updated are received, and executing the loading operation at the preset loading time.
As shown in fig. 6a, there is a preset loading time in the current cycle and also a preset loading time in the next cycle, if the update completion time 1 is in the same cycle as the preset loading time, for example, the current cycle, the update completion time 1 and the preset loading time are compared in the current cycle, and if the update completion time 1 is before the preset loading time, each modulation signal parameter is immediately updated, and the loading operation 1 is performed at the preset loading time.
In an optional embodiment, the method further includes:
step S402, acquiring the time length required for each path of modulation signal in the second type of modulation signal to update the modulation parameter to be updated;
step S404, summing up the required durations of all the second type modulation signals to obtain an updated duration of the second type modulation signal.
In the above alternative embodiment, steps S402 to S404 provide a method for determining whether the modulation signal parameter update crosses the preset loading time (loading point): and judging whether the time difference between the parameter updating starting moment and the preset loading moment is less than the updating duration of all the modulation signals (namely the time required for completing the updating of the parameters of the modulation signals), if so, determining that the parameter updating of the modulation signals needs to cross the preset loading moment.
Therefore, it is necessary to obtain in advance a required time length for each modulation signal in the second type of modulation signal to update the modulation parameter to be updated, and sum the required time lengths of each modulation signal in the second type of modulation signal to obtain an update time length of each modulation signal in the second type of modulation signal.
In an alternative embodiment, the controlling the second type modulation signal to perform a loading operation includes:
step S502, determining a preset loading time corresponding to each modulation signal in the second type of modulation signal, and an update completion time of each modulation signal, where the update completion time is a time for updating the modulation parameter to be updated;
step S504, determining whether a time difference between the update completion time and the preset loading time of each path of modulation signal in the second type of modulation signal is less than the update duration;
step S506, if yes, controlling each path of modulation signal in the second type of modulation signal to execute the loading operation at a loading time after the preset loading time; and if not, controlling each path of modulation signal in the second type of modulation signal to execute the loading operation at the preset loading moment.
Since the second-type modulation signals are modulation signals with different preset loading moments, it is necessary to determine a preset loading moment corresponding to each modulation signal in the second-type modulation signals and an update completion moment of each modulation signal, and determine whether a time difference between the update completion moment and the preset loading moment of each modulation signal in the second-type modulation signals is less than the update duration; if so, controlling each path of modulation signal in the second type of modulation signal to execute the loading operation at a loading time after the preset loading time; and if not, controlling each path of modulation signal in the second type of modulation signal to execute the loading operation at the preset loading moment.
As shown in fig. 6b, there is a preset loading time in the current cycle and also a preset loading time in the next cycle, but the update completion time 2 is not in the same cycle as the preset loading time, but spans two cycles or more cycles not shown in the figure, i.e. it needs to delay updating, for example, if the updating operation lasts from the current cycle to the next cycle, the loading operation 2 is not executed at the preset loading time of the current cycle, but the update completion time 2 and the preset loading time of the next cycle are compared in the next cycle (the last cycle where the update completion time 2 is located if it spans multiple cycles), if the update completion time 2 is before the preset loading time of the next cycle, each modulation signal delays to the preset loading time of the current cycle before updating, and performs a load operation 2 at a preset load time of the next period.
It should be noted that, if the update completion time 2 is completed from the current cycle across a plurality of cycles, the load operation 2 is performed at the preset load time of the last cycle at which the update completion time 2 is completed, and the update operation is performed after the preset load time of the cycle previous to the last cycle.
Specifically, for the second type of modulation signals with different preset loading moments, the parameter updating moment needs to be considered before or after the respective preset loading moments, and specifically depends on whether the parameter updating completion moment is before the preset loading moment or crosses the preset loading moment.
It should be noted that, if a path of modulation signal has multiple load points in one period, each load point should be updated after or before determining whether crossing is needed.
In the embodiment of the present application, the updating time of the modulation parameters of each modulation signal is optimized as much as possible, for example, in the embodiment of the present application, a parallel processor may also be used to update the modulation parameters of each modulation signal in parallel, so as to achieve the technical effect of reducing the waiting probability or delay for updating the modulation parameters.
Fig. 6c is a diagram obtained by combining two alternatives of fig. 6a and 6b, and since in actual operation, not only either one of fig. 6a or fig. 6b exists, but both cases may occur simultaneously or separately, the embodiment of the present application further provides a schematic diagram of combining two alternatives of fig. 6a and 6b as shown in fig. 6 c.
