초록

Due to their advantages of reduced cost, integrated multi-port converters (MPCs) with fewer components have received extensive attention. In this article, by extracting the concept of series/parallel input pulsating cells (IPCs) and output pulsating cells (OPCs), a set of syntheses for generating MPCs composed of IPCs and OPCs is proposed. When compared with the existing synthesis method for non-isolated MPCs, the proposed approach employs only one inductor and features single-stage power conversion between any two ports, which offers benefits in terms of compact size and high efficiency. Two design examples are shown to demonstrate the worth of proposed methodology. The operation principles are first analyzed. The pulsewidth modulation (PWM) and power control schemes are explained and designed in detail. To design the controllers, small-signal models for each of the operation modes are also extracted. Meanwhile, the characteristics of pulsating cells with different configurations are discussed and compared. The theoretical analysis is validated by simulation and experimental results for different operation conditions.
