在由初级H桥变换器、高频Transformer和H桥二极管整流器组成的DC/DC变换器中，直流变换比和Transformer利用率是低值。提出了一种采用软开关技术的单向隔离高频链DC-DC变换器。本文通过在次级二极管上并联谐振电容，提高了直流变换比和Transformer利用率。建议转换器的行为和设计的解释。所提出的转换器的有效性进行了验证，仿真和实验使用1千瓦，20 kHz的实验室原型。
In the DC/DC converter composed of a primary H-bridge converter, a high-frequency transformer and an H- bridge diodes rectifier, the dc conversion ratio and transformer utilization factor are low values. This paper presents a unidirectional isolated high-frequency-link DC-DC converter using soft switching technique. In this paper, the dc conversion ratio and transformer utilization factor are improved by the resonance capacitors connected to the secondary diodes in parallel. The behavior and design of the proposed converter are explained. The effectiveness of the proposed converter is verified by simulation and experiments using 1 kW, 20 kHz laboratory prototype.
