Abstract
The invention provides a control circuit, a control method, an air conditioner and a computer readable storage medium. The control circuit comprises a first control circuit body, a second control circuit body and an overvoltage protection circuit; the first control circuit body comprises a first capacitive element, and is configured to access the alternating voltage and convert the alternating voltage into the direct voltage; the second control circuit body comprises a second capacitive element, and is configured to control the alternating voltage to be input to the first control circuit bodyor stop power supply; the second capacitive element is configured to be able to withstand the maximum value of the alternating voltage, and a voltage withstanding value of the first capacitive elementis smaller than that of the second capacitive element; and the overvoltage protection circuit is connected between the first control circuit body and the second control circuit body, or integrated within the first control circuit body, and used for conducting overvoltage protection on the first control circuit body and / or the second control circuit body. Through the technical scheme, the production cost is effectively controlled while voltage resistance of the circuit is improved.
Description
technical field [0001] The present invention relates to the technical field of circuits, in particular, to a control circuit of an air conditioner, a control method of the air conditioner, an air conditioner and a computer-readable storage medium. Background technique [0002] Such as figure 1 As shown, the mains standard of domestic electricity in China is 220V, and the indoor electric control and outdoor electric control of the air conditioner are equipped with a 450V withstand voltage capacitor element. However, the mains standard of China's commercial electricity is 380V, 450V Capacitive elements may be damaged by overvoltage. [0003] related technologies, such as figure 2 As shown, the R&D personnel set the capacitive components on the indoor electric control and outdoor electric control to 500V withstand voltage, which will increase the production cost of the air conditioner and increase the layout area of the circuit board. [0004] In addition, any discussion ...
