Family of zero voltage transition interleaved converters with low voltage and current stress
IET Power Electronics, 2018 This study presents a family of zero voltage transition (ZVT) interleaved converters which utilises a simple auxiliary cell. The ZVT cell has only a single auxiliary switch for multi‐phase interleaved converters. In the proposed converters, all semiconductor devices operate under fully soft switching condition.
