Abstract：This paper proposes a dual active bridge (DAB) integrated Boost converter, and analyzes its working principle and soft switching under the PWM+phase shift control mode. By combining a plurality of dual active bridge integrated Boost converters, an input series output parallel (ISOP) type DC transformer is obtained that can be applied to the DC/DC link between the high voltage level DC bus and the hydrogen production cell in the electro-hydrogen multi-energy complementary microgrid. Through the combined control of the output voltage control loop, the input voltage regulation loop and the input voltage balance loop, the ISOP type DC transformer can achieve voltage equalization on the series side, voltage stability on the parallel side, and voltage matching between the primary and secondary sides of the transformer of each submodule. Based on the theoretical analysis, an experimental prototype with STM32+FPGA as the core controller is built. The experimental results have verified the correctness of the proposed topology and the effectiveness of the control strategy.
