Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
Fig. 1 shows a flowchart of a power regulation method based on an ac output power supply device provided in an embodiment of the present application (fig. 1 shows a first embodiment of the present application), and for convenience of description, only the parts related to the present embodiment are shown, and the detailed description is as follows:
a method of power regulation for an ac output-based power supply, comprising:
step S110, detecting the sum of the current input powers of all the loads, and recording the sum as power P1;
when the power supply device supplies power to the outside, it is necessary to detect the input power of all the loads to determine whether the current power supply device can carry all the loads.
Generally, outdoor mobile power supply equipment is provided with a plurality of alternating current output ports and a plurality of direct current output ports. The devices connected with the AC output port are generally lighting, small kitchen appliances and the like. Therefore, when the output power of the power supply device is insufficient, all the loads requiring the alternating current cannot be supplied with power.
When the power supply equipment supplies power to the outside, the current input power of all loads needing alternating current is detected, and the loads can continuously run under the current input power. If the load is too much, an overload situation may occur, and therefore, the current input power of all the loads needs to be summed and compared with the maximum output power of the power supply device to avoid overload.
Step S112, comparing the power P1 with the output power P2 of the power supply equipment, and if the power P1 is greater than the output power P2, the power supply equipment adjusts the output power of all loads.
The step of the power supply device adjusting the output power of all the loads comprises:
step S210, respectively obtaining the lowest input power of all loads;
step S212, adjusting the output power of the power supply equipment to one load of all loads to the lowest input power corresponding to the load;
step S214, repeating steps S110 to S112 until the power P1 is less than the output power P2, and the power supply device supplies power to all loads with the current input power corresponding to all loads.
When there are a plurality of loads of alternating current, and the sum of the current input powers of the loads exceeds the maximum output power of the power supply apparatus, it is necessary to detect the minimum input power of all the loads. The minimum input power refers to the minimum input power at which the load can maintain operation. For example, a load that is heated by a resistor can operate at the lowest input power, but it takes longer to heat to the user's desired temperature. Therefore, as long as the lowest input power of the load is detected, the corresponding input power can be given so that it can be continuously operated. When detecting that overload occurs when the load is supplied with the current input power, adjusting the input power of one load to the lowest input power corresponding to the load so that the load can normally operate.
And then continuing to detect the sum of the current input powers of all the loads until the sum of the powers is less than the output power of the power supply equipment.
For example, the power supply apparatus supplies power to a plurality of loads such as a lamp, an induction cooker, an electric cooker, or a coffee maker at the same time. When the load is detected to be powered by the current input power, the power supply equipment cannot meet the normal operation of all loads. Therefore, the power of the lamp is adjusted to the lowest input power by selecting the lamp for power adjustment. And then detecting that the power supply equipment can carry all the loads, and if the power supply equipment is not in operation, continuously selecting one of the loads to adjust to the lowest input power.
The power regulating method based on the alternating current output power supply equipment further comprises the following steps:
and controlling the AC output waveform of the power supply equipment to be kept as a sine waveform.
While the output voltage is reduced, the output waveform needs to be kept to be a sine waveform, and if the output waveform is not a sine waveform, the power supply equipment is easy to damage.
Please refer to fig. 2.
The step of the power supply device adjusting the output power of all the loads further comprises:
step S2102 of detecting types of all loads, and labeling the loads as pure resistive loads and inductive loads, respectively;
step S2104 of obtaining minimum input power of the pure electrical load and the inductive load, respectively;
step S2106, adjusting the output power of the power supply device to one of the pure resistive load and the inductive load to the lowest input power corresponding to the load.
Step S2106 includes:
and reducing the output voltage of the power supply equipment to enable the output power of the power supply equipment to be the lowest input power of one of the pure resistance type load and the inductive load.
Step S2106 further includes:
and if the load is an inductive load, controlling the output frequency and the current waveform of the power supply equipment to enable the output power to be equivalent to the lowest input power of one load of the inductive load.
That is, no matter the load is an inductive load or a resistive load, the voltage can be adjusted firstly under the condition that the output waveform of the power supply equipment is kept to be a sine wave, so that the input power of the load is the lowest input power, and the load operation can be maintained. The final purpose of the load is achieved by prolonging the working time. For example, a water heater, reduces the input voltage to the water heater, and in the same case, takes longer to heat the water to boiling.
When the load is inductive, after the input voltage is reduced, the input current waveform and the input frequency can be adjusted, so that the input current waveform and the input frequency are equivalent to the lowest input power, the effect of adjusting the power can be realized, and the power supply equipment can supply power to more loads.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
According to the power adjusting method based on the alternating current output power supply equipment, the sum of the current input powers of all the loads is detected, the sum of the current input powers is compared with the output power of the power supply equipment, if the sum of the current input powers is smaller than the output power of the power supply equipment, the power supply equipment is considered to be capable of carrying all the loads, and the power supply equipment normally outputs the power to the outside. However, when the sum of the powers is greater than the output power of the power supply device, it is determined that the power supply device is overloaded, and at this time, the lowest input power of all the loads needs to be detected, and the output power of all the loads is adjusted to the lowest input power corresponding to the load by the power supply device, so that the power supply device can carry all the loads, and thus, the normal output of the power supply device is ensured to meet the power supply requirement of the user.

the power detection module 301 is configured to detect the sum of current input powers of all loads, and record the sum as power P1; the power detection module 301 is further configured to send power P1 to the comparator module;

the power detection module 301 is further configured to obtain the lowest input power of all loads;
the controller 303 is configured to control the output power of the power supply device to one of all the loads to be adjusted to the lowest input power corresponding to the load.
After the power detection module 301 is configured to repeatedly detect the current input power of all the loads until the power P1 is less than the output power P2, the controller 303 is configured to control the power supply device to supply power to all the loads at the current input power corresponding to all the loads.
When the power supply device supplies power to the outside, it is necessary to detect the input power of all the loads to determine whether the current power supply device can carry all the loads.
Generally, outdoor mobile power supply equipment is provided with a plurality of alternating current output ports and a plurality of direct current output ports. The devices connected with the AC output port are generally lighting, small kitchen appliances and the like. Therefore, when the output power of the power supply device is insufficient, all the loads requiring the alternating current cannot be supplied with power.
When the power supply equipment supplies power to the outside, the current input power of all loads needing alternating current is detected, and the loads can continuously run under the current input power. If the load is too much, an overload situation may occur, and therefore, the current input power of all the loads needs to be summed and compared with the maximum output power of the power supply device to avoid overload.
The controller 303 is further configured to control the ac output waveform of the power supply apparatus to remain a sinusoidal waveform.
The power regulation system based on the ac output power supply device further includes a load detection module 304, where the load detection module 304 is configured to detect types of all loads and mark the loads as pure resistive loads and inductive loads, respectively; the load detection module 304 is further configured to send the marked pure resistive load and the marked inductive load to the controller 303;

the controller 303 is configured to control the output power of the power supply device to one of the pure resistive load and the inductive load to be adjusted to the lowest input power corresponding to the load.
The controller 303 is configured to control to decrease the output voltage of the power supply device so that the output power of the power supply device is the lowest input power of one of the pure resistive load and the inductive load.
If the load is an inductive load, the controller 303 is configured to control the output frequency and the current waveform of the power supply device, so that the output power is equivalent to the lowest input power of one of the inductive loads.
When there are a plurality of loads of alternating current, and the sum of the current input powers of the loads exceeds the maximum output power of the power supply apparatus, it is necessary to detect the minimum input power of all the loads. The minimum input power refers to the minimum input power at which the load can maintain operation. For example, a load that is heated by a resistor can operate at the lowest input power, but it takes longer to heat to the user's desired temperature. Therefore, as long as the lowest input power of the load is detected, the corresponding input power can be given so that it can be continuously operated. When detecting that overload occurs when the load is supplied with the current input power, adjusting the input power of one load to the lowest input power corresponding to the load so that the load can normally operate.

For example, the power supply apparatus supplies power to a plurality of loads such as a lamp, an induction cooker, an electric cooker, or a coffee maker at the same time. When the load is detected to be powered by the current input power, the power supply equipment cannot meet the normal operation of all loads. Therefore, the power of the lamp is adjusted to the lowest input power by selecting the lamp for power adjustment. And then detecting that the power supply equipment can carry all the loads, and if the power supply equipment is not in operation, continuously selecting one of the loads to adjust to the lowest input power.
Based on all the embodiments, the input power of the load is gradually adjusted in the above manner, so that the power supply device can carry all the loads, and the accurate control manner can supply power to the load with the optimal output power while the power supply device is not overloaded.
The power regulating system based on the alternating current output power supply equipment detects the sum of the current input powers of all the loads, compares the sum of the current input powers with the output power of the power supply equipment, and if the sum of the current input powers is smaller than the output power of the power supply equipment, the power supply equipment is considered to be capable of carrying all the loads, and the power supply equipment normally outputs the power to the outside. However, when the sum of the powers is greater than the output power of the power supply device, it is determined that the power supply device is overloaded, and at this time, the lowest input power of all the loads needs to be detected, and the output power of all the loads is adjusted to the lowest input power corresponding to the load by the power supply device, so that the power supply device can carry all the loads, and thus, the normal output of the power supply device is ensured to meet the power supply requirement of the user.
