Abstract
A compressor control apparatus includes a rectifying unit configured to rectify power applied from the outside, a DC link unit configured to include a pair of capacitors and smooth the rectified voltage, an inverter unit configured to include a pair of switches and convert the smoothed DC voltage into a driving voltage of a motor according to a control signal, and a control unit configured to generate the control signal, wherein the control unit applies a DC offset voltage to the driving voltage according to a direction of a current applied to the motor on the basis of a result obtained by comparing voltages across the pair of capacitors.
