Flexible‐structured phase‐shifted multiple‐full‐bridge DC–DC power supply with wide range output

A novel hybrid topology with the optimised structure for wide range output power supply is proposed in this study. The phase‐shifted multiple‐full‐bridge (PSMFB) converter is composed of multiple full‐bridge DC–DC power converters and high‐frequency transformers. For different requirements, it guarantees the power capacity with several smaller high‐frequency transformers and a smaller filter by a PSMFB with proper design. With the control strategy of only one phase‐shifted controller, all the modules can fulfil the output change with the phase‐shifted angle. The effectiveness of the proposed converter was verified using simulation and experimental results of a 1 kW converter system.
