Title:
CONTROLLER, AIR CONDITIONER, AND HIGH-VOLTAGE PROTECTION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/218266
Kind Code:
A1
Abstract:
Provided in the present application are a controller, an air conditioner and a high-voltage protection circuit. The controller comprises a first rectifier unit, a power source conversion unit, an HPS wiring terminal, a low-voltage control unit and a high-voltage working unit, wherein an input end of the first rectifier unit can be electrically connected to an input power source, an output end of the first rectifier unit can be electrically connected to an input end of the power source conversion unit, and the first rectifier unit converts an input alternating current into a high-voltage direct current and outputs same to the power source conversion unit; an output end of the power source conversion unit can be electrically connected to a power supply end of the low-voltage control unit, the power source conversion unit converts the high-voltage direct current into a low-voltage direct current and outputs same to the power supply end of the low-voltage control unit, so as to supply power to the low-voltage control unit; the HPS wiring terminal can be electrically connected to a pressure switch, and the HPS wiring terminal is connected to a front end of a power supply end on a power source input side of the low-voltage control unit; and an output end of the low-voltage control unit is connected to a control end of the high-voltage working unit. The controller has a high-voltage protection function.
