摘要：
In this letter, we introduce a simple turn-ON snubber for the conventional bidirectional converter. This snubber notably reduces the current reduction rate of the converter main diodes at turn-OFF. Hence, the reverse recovery losses, which are the dominant losses in the bidirectional converter, are almost eliminated. These features are achieved with a minimum circulating current and no extra voltage or current stress. The conventional bidirectional converter with the proposed snubber is analyzed, and to confirm the analysis, the experimental results are presented.
