Abstract
A compressor control apparatus, and a compressor control method. The compressor may be operated in an operation mode in which commercial power applied to the compressor does not pass through an alternating current capacitor when the load is in an overload state, thereby preventing the loss of a drive and effectively reducing the copper and core loss of the compressor.
