Control apparatus for controlling motor of air conditioner |
摘要 |
A control apparatus for controlling a motor of an air conditioner includes a converter (2), having switching means (2a) for improving an input power factor, for converting an AC power to a DC power and an inverter (4) for converting the DC power supplied from the converter to the AC power and supplying to a compressor (3). The output DC voltage of the converter is detected by a DC voltage detecting circuit. An input alternating current is detected by a current detecting circuit (11). A microcomputer (13) for controlling the inverter calculates a current command from data stored on the basis of the detected voltage. The detected current is compared with the current command, an ON percentage of a PWM signal to control the switching means is obtained, and the PWM signal is generated. <MATH> |
