Document Type and Number:
WIPO Patent Application WO/2020/220771
Kind Code:
A1
Abstract:
Provided in the present application are a drive control circuit and an air conditioner, the drive control circuit comprising: a first capacitive element and a switching element; the first capacitive element is configured to provide a start-up voltage of a motor assembly of an air conditioner; the switching element accesses an input line of the first capacitive element, wherein if the switching element is turned on, a power grid system charges the first capacitive element, and the on-time of the switching element is directly correlated with the charging voltage of the first capacitive element. By means of the technical solution provided in the present application, there is no need to provide a relay and a thermistor in the drive control circuit of the motor assembly, which thereby reduces the hardware loss and power consumption of the switching element, and reduces the layout area of a circuit board.
