Multi-cell multi-port bidirectional flyback based on GaN devices

Abstract

This paper proposes the novel Multi-cell Multi-port Bidirectional Flyback (M2BF), which is suitable for applications with high-controllability requirement. Moreover, control strategy of the proposed converter and design considerations are analyzed, identifying the most differential characteristics. The main advantage of M2BF is the possibility of configuring the number of connected cells according to the specifications of the system. Besides, an independent control of each cell is proposed with a bidirectional power flow. The assembled experimental prototype is also presented, in order to validate the proposed concept.
