Abstract
이 발명은 전원공급장치에 관한 것으로서, 스위칭 트랜지스터를 바이폴라로 사용하면 높은 스위칭 상승이 어렵고, 트랜지스터의 손실이 크며, 완벽한 차단이 어려운 문제점이 있으므로 이를 해결하기 위한 이 발명은, 2차측에 에너지를 전달하기 위한 단속 모드용 스위칭 전계효과 트랜지스터와, 상기 스위칭 트랜지스터 2개가 토글식으로 온오프되도록 제어하는 펄스폭 변조 집적회로의 출력단자에 연결된 스위칭 제어부와, 펄스폭 변조 집적회로의 전원공급단자에 연결되어 초기구동과 전압을 공급하는 초기구동 및 전압공급부로 구성되어 전계효과 트랜지스터를 사용함으로써 1차측에서 구동이 가능하다.The present invention relates to a power supply, and when the switching transistor is used as a bipolar, there is a problem that a high switching rise is difficult, a loss of a transistor, and a complete blocking is difficult. Therefore, the present invention for solving this problem transfers energy to a secondary side. A switching field effect transistor for an intermittent mode, a switching controller connected to an output terminal of a pulse width modulation integrated circuit for controlling two switching transistors on and off in a toggle mode, and a power supply terminal of the pulse width modulation integrated circuit. It is composed of initial drive and voltage supply part that supplies initial drive and voltage, and can be driven on the primary side by using a field effect transistor.
