“…Besides, by interleaving n phases, the effective switching frequency is increased n times. As a result, the transient response is improved and the passive components size and weight are reduced [1,2]. Therefore, interleaved topologies are very attractive in high power applications like power factor correctors (PFCs), voltage regulators, and renewable energy systems [3][4][5][6][7].…”

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. The main switches turn on and turn off under zero voltage switching (ZVS) condition while the auxiliary switch turns on and turns off under zero current switching (ZCS) condition. Besides, all the converter main and auxiliary diodes turn off under ZCS condition which alleviates the diodes reverse recovery problem. The ZVT cell imposes no extra current and voltage stresses on the semiconductor devices. The effectiveness of the proposed method is evaluated by a 100 kHz, 200 W two-phase interleaved boost converter and the theoretical analysis and design procedure are discussed in detail. Furthermore, the results of an implemented laboratory prototype are provided which are consistent with the theoretical analysis.
