Abstract

Actually, The hard switching high frequency PWM DC-DC converters are existing accompany, the high frequency of pulse modulation carrier frequency increase of switching loss of power semiconductor switching elements, there are have some problem points of EMI etc. This compliance with a voltage surge or the electric current surge are where the switching transient phenomenon accompanies. In order to solve like this problem effectively it described the principle of operation of New Small Scale Boost PWM Chopper circuits from the present paper, draw Characteristics from simulation and experiment.

기존의 하드 스위칭 고주파 PWM DC-DC 컨버터는 펄스 변조 캐리어 주파수의 고주파화를 수반하고, 전력용 반도체 스위칭 소자의 스위칭 손실의 증대나 스위칭 과도현상이 수반된 전압 서지나 전류 서지에 의한 EMI 등의 문제점들이 있다. 이러한 문제를 효과적으로 해결하기 위해 본 논문에서는 새로운 소용량 승압형 PWM 쵸퍼 회로의 동작원리를 서술하고, 시뮬레이션과 실험을 통하여 특성을 도출하였다.
