Abstract

본 발명은 하프브리지 변환회로에 관해 게시한다. 종래에는 과전류 보호회로가 내장되어 있지 않아서 과전류가 발생할 경우 회로가 비정상적으로 작동할 수가 있는데 반해 본 발명은 과전류 보호회로가 내장됨으로써 과전류로부터 회로를 보호할 수 있을 뿐만 아니라 전력소모도 감소시킬 수가 있다.The present invention relates to a half bridge conversion circuit. Conventionally, since the overcurrent protection circuit is not built in, and an overcurrent occurs, the circuit may be abnormally operated. However, the present invention may not only protect the circuit from overcurrent but also reduce power consumption by incorporating the overcurrent protection circuit.
