摘要：
A high-voltage full bridge dc-dc converter has a big problem of high-voltage surge occurrence across secondary-side rectifying diodes. In order to solve this problem, a simple solution with a snubber capacitor has been proposed. This technique provides a prominent effect of surge-voltage suppression. On the other hand, it deteriorates the control characteristics of this converter. In this paper, the control characteristics are analyzed by the state-space averaging method. Based on this analytical result, the improvement of the control characteristics is proposed. Some experiments confirm the effectiveness of the proposed technique.
