Abstract

본 발명은 인버터회로에서 초기전우너인가시 돌입전류에 의해 발생하는 전원단락현상에 의한 회로의 파괴현상을 방지하도록 한 인버터회로의 초기과전류 보호회로에 관한 것이다.The present invention relates to the initial overcurrent protection circuit of the inverter circuit to prevent the destruction of the circuit caused by the power supply short circuit phenomenon caused by the inrush current when the initial electric voltage applied to the inverter circuit.

종래의 인버터회로의 초기과전류 보호회로는 회로가 복잡하고, 많은 부품이 소요되므로 코스트가 상승되며, 기판차지면적이 크다는 단점이 있었던 점을 감안하여 본 발명은 인터버회로의 초기과전류 보호회로에 있어서, 전원에 연결되어 초기 돌입전류를 제한하는 써미스터와, 상기 써미스터를 통한 전원전압이 기준전위 이상이 되면 턴온되는 다이악으로 되는 제1스위칭소자와, 상기 제1스위칭소자 턴온시 턴온되어 본회로측으로 전원전압이 인가되도록 하는 트라이악으로 되는 제2스위칭소자로 인버터회로의 초기과전류 보호회로를 구성함으로써 종래에 비해 간단한 회로 구성으로 인버터회로의 초기과전류 보호기능을 할 수 있도록 한 것이다.In view of the fact that the initial overcurrent protection circuit of the conventional inverter circuit has a disadvantage in that the circuit is complicated, many parts are required, the cost is increased, and the board area is large. A thermistor connected to the power supply to limit the initial inrush current, a first switching device to be a diaak that is turned on when the power supply voltage through the thermistor is equal to or higher than the reference potential, and turned on when the first switching device is turned on to the main circuit side. The second switching device, which is a triac, which allows the power supply voltage to be applied, constitutes the initial overcurrent protection circuit of the inverter circuit, thereby enabling the initial overcurrent protection function of the inverter circuit with a simpler circuit configuration than in the related art.
