Abstract
An apparatus and method for controlling a compressor are provided. A motor current flowing in a compressor may be calculated from voltage values of a capacitor without using a sensor, and as a motor current value is calculated by changing voltage values of the capacitor according to voltage values of a drive and performing a definite integral thereon, the motor current value may be resistant to noise, and the compressor may be more stably controlled.
