Abstract

The invention provides a controller, an air conditioner and a method for supplying power to the controller by using direct current, wherein, the controller comprises a first conversion circuit connected with an external direct current power supply for converting the received external direct current voltage to a first voltage; A second conversion circuit connected to an external DC power supply forconverting the received external DC voltage to a second voltage; Wherein the first voltage is greater than the second voltage; A third conversion circuit connected to the second conversion circuit for converting the second voltage to the third voltage; Wherein the second voltage is greater than the third voltage, and the first voltage and the third voltage are used for supplying power to the load. The invention solves the problem of low power supply efficiency caused by adopting alternating current power supply for household air conditioning, and further achieves the effect of improving powersupply efficiency.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a controller, an air conditioner and a method for supplying power to the controller with direct current. Background technique [0002] At present, the internal units of household air conditioners are powered by 220V AC. figure 1 It is a schematic diagram of a circuit powered by 220V AC in the related art, such as figure 1 As shown, in the related art, 220V AC is used for power supply, and 15V and 12V are obtained through a strong current filter-rectifier bridge-switching power supply circuit, which supplies power to corresponding loads, and 12V is then converted into 5V. In addition, the communication mode adopted by the internal and external units of the air conditioner in the related art is a zero live wire communication circuit. However, the AC power supply method in the related art requires a strong current filter-rectifier bridge-switching power supply circui...
