Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Non-conflicting ones of the following embodiments may be arbitrarily combined.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of an adjusting device provided in the present application, where the adjusting device 1 includes: a power supply circuit 10, a main control circuit 20, and a switch circuit 30. The power circuit 10 includes a zero point detection module 110, the power circuit 10 is used for externally connecting an alternating current to provide a working power supply for the adjustment device 1, and the zero point detection module 110 is used for detecting a zero point of the accessed alternating current to generate a zero point signal ZT.
The ac power is typically a common 50HZ or 60HZ sine wave ac mains output. The power circuit 10 may include a rectifier module (not shown) for converting ac power to dc power. Optionally, the power circuit 10 may further include a voltage boosting module (not shown) and/or a voltage dropping module (not shown) for converting the dc power output from the rectifying module into dc power suitable for driving the components in the regulating device 1. The zero point detection module 110 may include an optical coupler capable of detecting a zero point of a voltage amplitude of the external ac power to generate a zero point signal. Specifically, the zero point signal may be a square wave signal having the same frequency and phase as the alternating current, that is, the zero point of the square wave signal is the same as the alternating current, the voltage of the alternating current is positive, the square wave signal is also positive, and when the voltage of the alternating current is negative, the square wave signal is negative.
The main control circuit 20 is coupled to the power circuit 10, and configured to receive the zero point signal generated by the zero point detection module 110 and sent to the main control circuit 20 and n adjustment signals a1, …, An, n, which are positive integers greater than 1. The main control circuit 20 can determine the transmission mode corresponding to the n trigger signals based on the zero point signal and the n adjustment signals, and transmit the n trigger signals CT1, …, CTn according to the transmission mode.
The switch circuit 30 includes n independent power switch modules 310, …,3n 0. Each power switch module receives a trigger signal of the main control circuit 20, is coupled to a load powered by ac power, and changes the conduction state of the power switch module under the action of the trigger signal to change the conduction state of the corresponding load, thereby realizing adjustment of the working state of the load. For example, the power switch module 3i0 receives the trigger signal CTi and is coupled to the load i, i is 1, …, n, and changes the conducting state of the power switch module 3i0 under the action of the trigger signal CTi to change the conducting state of the corresponding load i, thereby implementing the adjustment of the operating state of the load i.
For convenience of illustration, the adjustment signal corresponds to the trigger signal, the power switch module and the load one to one in the present embodiment, and in practical applications, the adjustment signal does not necessarily correspond to the trigger signal, the power switch module and the load one to one.
The power switch module 3i0 may be a switch control module comprising a thyristor. A Silicon Controlled Rectifier (SCR) is a high-power electrical component, also called a thyristor. Optionally, the thyristor in this embodiment may be a bidirectional thyristor, also called a TRIAC, which is called a TRIAC for short, has a bidirectional conduction function, and may be used as an ac switch, and the on-off state of the TRIAC is determined by the control electrode. The two electrodes of the thyristor are coupled with alternating current, a pulse trigger signal is applied to a control electrode (also called a gate electrode) of the thyristor, and the thyristor is conducted until the thyristor is closed at the next alternating current zero point. The conduction state of the controllable silicon can be controlled by controlling the sending time of the trigger signal, so that the working state of the load can be adjusted.
In an embodiment, specifically, the main control circuit 20 may be configured to detect the adjustment signal to obtain a state value of the corresponding load, and determine the transmission mode according to the state value. Wherein the transmission mode includes when to transmit the trigger signal.
The status value represents the current goal of load operating state adjustment. Generally, the kind of the state value of one load is greater than or equal to 2. When the type of the state value is 2, the state value represents an on state and the state value represents an off state. When the type of the state value is more than 2, besides the two states of representing the opening state (namely, the full load operation) and representing the closing state, the intermediate state also has an intermediate state, the load of the intermediate state is still in operation but not full load, namely, the value of the operation parameter is smaller than the opening state. The operating parameter may be speed, light intensity, temperature, etc., depending on the type of load.
The voltage value of the adjustment signal may be directly indicative of the state value, e.g., high for on low for off; or detecting whether the adjusting signal has effective pulse, if yes, indicating that the state value is changed into the next one; or decode the adjustment signal to obtain the state value.
Generally, the on-state of the power switch module can be controlled by the trigger signal to adjust the power/equivalent voltage of the load, so as to adjust the working state of the load.
According to the operating principle of the thyristor described above, if the trigger signal is not sent or sent before each zero point of the alternating current and the trigger signal is sent at the moment before the zero point infinitely approaches, the thyristor in the power switch module is always off, the equivalent voltage of the load is 0, and the load is in the off state. In the case where the trigger signal is sent immediately before each zero point of the alternating current, the voltage waveform of the alternating current supplying the load under the control of the power switch module during one alternating current period is as shown in fig. 2, and the equivalent voltage of the alternating current during one alternating current period is approximately zero. If the trigger signal is continuously sent or the trigger signal is sent at each zero point of the alternating current, the controllable silicon in the power switch module is always conducted, the equivalent voltage of the load is the equivalent voltage of the alternating current, and the power switch module is in an on state. In the case where a trigger signal is sent at each zero point of the alternating current, the voltage waveform of the alternating current supplying the load under the control of the power switch module in one alternating current period is as shown in fig. 3, and the alternating current is outputted as a complete waveform in one alternating current period.
For the intermediate state, the state value may be an adjustment ratio, that is, a ratio of the load power corresponding to the adjustment signal to the full load power of the load, and at this time, there may be two ways to adjust the equivalent voltage: chopper regulation and zero-crossing regulation.
Under the condition of chopping adjustment, the sending mode is that the trigger signal is sent after the first time length is delayed by taking the zero point of the alternating current as a reference, the silicon controlled rectifier is in a closed state from the zero point of the alternating current to the first time length, and the silicon controlled rectifier is in an open state from the first time length to the next zero point. An example of the voltage waveform of the ac power supplied to the load under control of the power switching module during an ac cycle, with chopping regulation and with the load in an intermediate state, is shown in fig. 4, with the ac power being partially output during an ac cycle. The ratio of the first duration to the period of the alternating current also reflects the phase position where the silicon controlled rectifier starts to be conducted, and corresponds to the conduction angle of the silicon controlled rectifier. The longer the first time length is, the shorter the conduction time of the controllable silicon is, the smaller the equivalent voltage of the load is, the smaller the power is, the smaller the corresponding regulation ratio is, and the first time length is known to be inversely related to the regulation ratio.
Under the condition of adopting zero-crossing adjustment, the transmission mode is that a zero point of a alternating current sends a trigger signal in an adjustment period (including a period of b alternating currents), a and b are positive integers, a is less than or equal to 2b, the trigger signal is not sent in the rest zero point or sent in the previous moment of the corresponding next zero point, so that the silicon controlled rectifier is conducted in a/2 periods in the period of b alternating currents, the rest periods are not conducted, and the adjustment ratio is equal to a/2 b. For example, as shown in fig. 5, taking b as 3 and a as 4 as an example, when zero-crossing regulation is performed on the load, the current sending mode is that a period of 3 alternating currents is used as one regulation period, and the trigger signal is sent only at the zero point of 4 alternating currents in one regulation period, then correspondingly, in the period of 3 alternating currents, that is, one regulation period, the thyristor is in a conducting state only in 2 periods of the alternating currents, the rest periods are not conducting, the current regulation ratio is equal to 4/(2 × 3), that is, the current regulation ratio is equal to 2/3.
The main control circuit 20 may determine the transmission timing of the trigger signal with respect to the zero point of the alternating current according to the state value, and in combination with the zero point of the alternating current provided by the zero point signal, may determine the specific transmission timing of the trigger signal, and accordingly transmit the trigger signal.

In this way, the adjusting device can adjust at least two paths of loads simultaneously in the application, so that the working state of the multi-path loads can be adjusted by using one adjusting device more conveniently, the wiring of a multi-path load adjusting loop and the configuration resources of the corresponding adjusting device are effectively saved, and the multi-path load adjusting loop is wider in applicable field and more practical.
