FB-ZVT PWM 컨버터의 환류구간 손실저감을 위한 보조회로 = The Auxiliary Circuit for Reducing Loss during Free-Wheeling Intervalin FB-ZVT PWM Converter

다국어 초록 (Multilingual Abstract)

In this paper proposes a FB(full bridge) ㆍ<br/>
DC-DC converter which uses a saturable reactor, instead of two additional switches, to achieve zero voltage switching. And, the conventional high frequency phase shifted full bridge ZVT (zero voltage transition) DC-DC converter has a disadvantage that a circulating current flows through high frequency transformer and switching devices during the free-wheeling interval. Due to this circulating current, conduction loss increases. In order to reduce such the loss as this, proposes circuit of reducing conduction loss at the secondary side of transformer. The operation principles are explained in detail and the several interesting simulations and experimental results verify the validity of the proposed circuit.
