ABSTRACT:
A drive control apparatus for controlling a motor to drive the compressor of an air conditioner, according to the present invention, includes a rectifying circuit for converting an AC voltage into a DC voltage, an inverter having a combination of a plurality of power controlling semiconductor devices and which controls the DC voltage from the rectifying circuit in accordance with a drive signal supplied to the combination of the semiconductor devices so as to generate an AC drive current to the drive, and a drive circuit for generating the drive signal to the inverter. The drive circuit formed as a monolithic integrated circuit having a dielectric separation structure, with the monolithic integrated circuit and the inverter being mounted on a common module substrate.
