Abstract

Bidirectional DC/DC converters are so prevalent in several applications. Regarding some applications, increasing their voltage gain ratios (VTR) are quite important. So, this paper proposes a novel extendable bidirectional boost-buck converter. In this converter, any isolation and coupled inductors are not employed. Each stage is derived from fundamental bidirectional boost/buck converter with the same switching algorithms. By embedding n stages in topology, VTRs for step-up/step-down are multiplied n times for step-down and step-up modes. Furthermore, a comprehensive comparison have provided in case of VTR and total voltage stress across active power switches. It can be seen that total voltage stress of active power switches (TVSAPS) is much lower than the other relevant structures. The feasibility of this architecture has successfully examined by PSIM simulation and detected experimental outcomes from prototype laboratory set up.
