【Abstract】 Passive lossless energy recovery in VSI bridge legs is investigaed. The analyses on topological nature and operational principle are given in detail. A coupled inductance component is adopted that delivers the snubber energy stored in a relatively large capacitor via resonant forward conversion principle.更多还原
