The microcomputer outputs a compressor driving control signal according to the output value and whether the set time has elapsed, and the compressor driving unit drives the compressor by switching the power supply to the main winding or the auxiliary winding according to the control signal of the microcomputer.

또한 본 발명에 따른 압축기 기동방법은 압축기 운전시점으로 판단될 경우 압축기의 주권선과 보조권선에 전원을 공급하여 기동시키는 단계와, 압축기 기동상태에서 설정된 시간이 경과하였는지를 체크하고 주권선의 현재 전류값을 측정하는 단계와, 측정된 주권선의 전류값을 압축기의 완전 기동시점에서 설정된 규정치와 비교하여 같을 경우 보조권선의 전류를 차단시키는 단계와, 측정된 주권선의 전류값이 설정된 기준치 이상인지를 판단하여 그 이상일 경우 주권선의 전류를 차단시키는 단계로 이루어짐을 특징으로 한다.In the compressor starting method according to the present invention, if it is determined that the compressor is operating, the step of supplying power to the main winding and the auxiliary winding of the compressor is started, and checking whether the time set in the compressor starting state has elapsed and measuring the current value of the main winding. Comparing the measured current value of the main winding with the prescribed value set at the start of the compressor, and shutting off the current of the auxiliary winding; and determining whether the measured current value of the main winding is greater than or equal to the set reference value. In this case, the main winding is characterized in that the step consisting of blocking the current.
