<P>PROBLEM TO BE SOLVED: To provide a control device for an air conditioner that shortens a test time on a production line. <P>SOLUTION: The control device for an air conditioner includes: a rectification circuit 7 for rectifying a commercial AC voltage; a smoothing capacitor 9 for smoothing the voltage rectified by the rectification circuit 7 to a DC bus voltage; an inverter section 11 for converting the DC bus voltage to an AC voltage of an arbitrary frequency to drive a compressor motor 12; a transformer 10 for generating a control supply voltage from the DC bus voltage; and a control section 8 operable on the control supply voltage to control the drive of the inverter section 11 at an external command. The control section 8 continuously performs restrained compressor motor energization of applying a low torque insufficient to operate the compressor motor 12 at an external restrained compressor motor energization command. <P>COPYRIGHT: (C)2013,JPO&INPIT |
