Detailed Description
The present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the examples provided herein are merely illustrative of the present application and are not intended to limit the present application. In addition, the following examples are provided as partial examples for implementing the present application, not all examples for implementing the present application, and the technical solutions described in the examples of the present application may be implemented in any combination without conflict.
Fig. 1 is a diagram illustrating an application scenario of an air conditioner control method according to an embodiment of the present application. Referring to fig. 1, a main control panel of an outdoor unit of an air conditioner supplies power to devices such as a main chip by using a flyback switching power supply circuit 101, the flyback switching power supply circuit 101 is a common switching power supply topology circuit, and when a switching tube is turned on, the circuit only stores energy but does not transfer the energy; when the switching tube is turned off, the stored energy is transferred to the load. After the circuit is started, the auxiliary winding supplies power to the switching power supply chip to form self-excitation feedback, and normal and stable operation of the circuit is guaranteed.
For example, the input circuit of the flyback switching power supply circuit 101 is connected with ac power, rectified by the strong current filter circuit and the rectifier bridge, and then the electric energy of the rectified dc power is stored by a plurality of large-capacity electrolytic capacitors, which are charged and discharged in the output circuit of the flyback switching power supply circuit 101 and supplied to the load 102 of the air conditioner.
It should be understood that the switching power supply chip of the flyback switching power supply adjusts the waveform of the dc signal in the output loop according to the feedback signal of the voltage change, including the adjustment of the duty ratio or the adjustment of the frequency, so as to change the voltage of the output loop in the opposite direction, thereby ensuring the stability of the dc signal in the output loop.
Illustratively, the load 102 of the air conditioner includes any one of the following loads: the air conditioner comprises a compressor of the air conditioner, a direct current fan of the air conditioner and a condenser of the air conditioner.
It should be understood that, when the air conditioner suddenly fails or is abnormally powered off, the ac voltage at the input terminal of the flyback switching power supply circuit 101 is 0, and the outdoor unit main control board stops working. However, the charge capacity stored in the electrolytic capacitor is large, and when the power demand of the load 102 of the air conditioner is suddenly interrupted, the electric energy stored in the electrolytic capacitor has no release path, and there is residual electric energy in a certain time, and the residual electric energy flows back to the switching power supply chip through the primary side of the high-frequency transformer, so that the switching power supply chip is damaged by overcurrent.
