Abstract

본 발명의 선형 압축기 제어장치는, 양단에 제1 및 제2트라이악이 병렬 연결된 제2모터권선과, 상기 제2모터권선과 직렬연결됨과 동시에 제2트라이악과 연결된 제1모터권선과, 정상운전시에는 상기 제1트라이악을 선택하여 제1 및 제2모터권선을 구동하고, 공진시에는 상기 제2트라이악을 선택하여 제1모터권선만 구동하다록 함으로써 권선수를 감소시켜 트라이악 구동기간을 확보하도록 하기 위한 스위칭부와, 상기 스위칭부를 제어하기 위한 전류제한부를 포함하여 구성되며, 공진시에도 트라이악 구동기간을 확보함으로써 냉장고에 적용하는 경우, 소비전력 감소 특성을 유지하면서 변속운전시 생기는 출력저감을 개선할 수 있으며, 고속냉각능력을 향상시킬 수 있는 효과가 있다.The linear compressor control apparatus of the present invention includes a second motor winding in which first and second triacs are connected in parallel at both ends, a first motor winding connected in series with the second motor winding and connected to a second triac, and during normal operation. The first triac is selected to drive the first and second motor windings, and when the resonance occurs, the second triac is selected to drive only the first motor winding so that the number of turns is reduced to increase the triac driving period. It is configured to include a switching unit for ensuring and a current limiting unit for controlling the switching unit, when applied to the refrigerator by securing the triac driving period even during resonance, the output generated during the shift operation while maintaining the power consumption reduction characteristics The reduction can be improved, and the high-speed cooling ability can be improved.
