In this paper, we designed high performance, high quality and high density switch mode power supply for precision electronics, and communication equipments. For this, we used two parallel DC-DC converters, which have opposite phases, to support proper high performance and high quality power. To reduce switching losses and make high switching frequency, active-clamp and ZVS technique were employed in each converter.

This paper presents a novel circuit topology of the double two-switch forward type high frequency transformer linked soft-switching PWM DC-DC power converter with tapped inductor filters that can operate under a condition of the low peak voltage stress across the power semiconductor devices and lowered peak current stress through the transformer for some high power applications. This circuit topology of an interleaved two-switch forward soft-switching power converter is proposed in the order to minimize an idle circulating current due to the tapped inductor filter without of any additional active auxiliary resonant-assisted snubber circuits, such as active resonant DC link snubbers and AC link snubbers, active resonant commutation leg link snubbers. The unique advantages of this power converter are less power circuit components and power semiconductor devices, constant frequency PWM scheme, cost effective configuration and wider soft-switching PWM operation range under PWM power regulations load variations. The practical effectiveness of the proposed soft-switching converter circuit topology is tested by simulations and is proved by experimental results received from the 500W-100kHz breadboard setup.

본 논문은 낮고 넓은 입력 및 높은 출력 전류를 가지는 어플리케이션에 적합한 새로운 인터리브드 액티브 클램프 포워드 컨버터를 제안한다. 컨버터는 직렬로 연결된 2차측 추가 권선을 이용하여 0.5이상의 시비율로 동작할 수 있으며, 추가 플로팅 게이트 구동회로 없이 2차측 동기 정류기를 구동할 수 있다. 제안된 회로의 유효성은 36-72V 입력 12V/500W 시제품을 통해 검증하였다.
