| Popis: | This paper presents a family of zero voltage transition (ZVT) interleaved dc–dc converters. Soft switching operation for all power semiconductor devices in the proposed topologies is achieved by using one auxiliary circuit with only one auxiliary switch. Therefore, the proposed converters have a simple structure with low size and cost. The proposed converters can achieve zero voltage soft switching operation for the main switches and zero current soft switching operation for the auxiliary switch. In addition, the reverse-recovery problem of the diodes is alleviated. Therefore, the losses associated with semiconductor components are reduced and efficiency is improved considerably. Besides, no extra voltage and current stresses are imposed on the main switches in comparison with hard switching counterparts. Operation principles and design considerations of an interleaved boost converter with the ZVT auxiliary circuit are discussed in detail. A prototype of this converter is implemented and tested to validate the theoretical analysis and converter operation. |
