摘要：

A major problem in high-voltage full bridge dc-dc converters is the high-voltage surge that occurs across the secondary-side rectifying diodes. In order to solve this problem, a simple solution with a snubber capacitor has been proposed. This technique provides effective surge-voltage suppression. On the other hand, it degrades the control characteristics of this converter. In this paper, the control characteristics are analyzed by the state-space averaging method. On the basis of this analytical result, a novel technique for control characteristics improvement is proposed. Experiments confirm the effectiveness of the proposed technique.
