Abstract: An apparatus and a method may control a compressor. The apparatus may control a motor (included in a compressor) such that the motor quickly repeats turn-on and turn-off operations in a cooling power supply time period/section, thereby enabling the compressor to compress refrigerant in the cooling power supply time period/section. Thus, cooling power of a refrigerator may change while the compressor operates with maximum efficiency.

Abstract: A method and an apparatus may detect a rotor magnetic pole of a single-phase BLDC motor. The method and apparatus may quickly and precisely initially drive the single-phase BLDC motor by detecting a position of a magnetic pole of a rotor adjacent to a stator by applying a high frequency voltage to the single-phase BLDC motor and analyzing a magnitude of a flowing current.
