駆動制御回路、エアコン及びコントローラ
Document Type and Number:
Japanese Patent JP7182719
Kind Code:
B2
Abstract:
The present application provides a drive control circuit, an air conditioner and an air conditioner controller. The drive control circuit comprises an inverter bridge used for outputting a drive signal, the inverter bridge being connected in series between a high-voltage bus and a low-voltage bus. The control circuit further comprises: a reactor used for absorbing a surge signal generated during the operation of a load driven by the drive control circuit, the reactor being connected between a power grid and the load; and a bus capacitor used for filtering out the surge signal on a bus line, the bus capacitor being connected to the bus line at an input side of the inverter bridge. In the technical solution provided by the present invention, an electrolytic capacitor having high cost is replaced with a thin film capacitor having low cost, prolonging the service time of the drive control circuit, reducing the occurrence of control efficiency reduction caused by heating of the bus capacitor, and improving the reliability and operation efficiency of the drive control circuit.
