Claims (4)

  1. 하나의 전자 스위치에 대해 직렬로 놓인 인덕터와 전자 스위치를 통해 흐르는 전류를 측정하기 위한 전류센서를 가지며, 상기 전류가 미리 정해진 최대치를 초과할때 전자스위치를 도통하도록 제어하는 펄스가 차단되는 회로에 있어서, 전류의 미리 정해진 최대값에 대한 동작문턱값이 회로에 공급되는 인력전압에 의존해서 자동으로 변화될 수 있는 것을 특징으로하는 스위칭파워 서플라이.
  2. 제1항에 있어서, 입력전압이 상승할때 미리 정해질 수 있는 동작문턱값이 하강하며 그역도 또한 같은 것을 특징으로하는 스위칭파워 서플라이.
  3. 제1항 및 2항에 있어서, 동작문턱값은 비교기를 통해 발생되며, 그 한 입력단에는 기준전압이 공급되고 그 다른 입력단에는 회로의 입력전압에 의존하는 전압이 공급되며 그것에는 또한 센서에 의해 유도되는 전압이 인가되는 것을 특징으로하는 스위칭 파워 서플라이.
  4. 제1항 및 2항에 있어서, 동작문턱값은 비교기를 통해 발생되며, 그 한 입력단에는 전류센서에 의해 유도된 전압이 공급되며, 다른 입력단에는 기준전압이 인가되고, 그 값은 회로의 입력전압에 의존해서 입력전압이 증가할때는 줄어들고 그 역도 그와 같은 방법으로 변화될수 있는 것을 특징으로하는 스위칭 파워 서플라이.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
