Abstract

The multi-module series-parallel combination system suitable for high voltage and large current has good application effect and performance level, high research value, and vast prospects. In this paper, an isolated full-bridge DC/DC converter is used as a single module to form an Input series output paralleled (ISOP) combined system. A three-loop control strategy is designed to achieve the input voltage sharing and output current sharing of the system. The simulation models of the three modules are established by MATLAB Simulink, and the voltage jump experiment is carried out. The experimental results show that the three-loop control strategy has a good setting effect, which can ensure the system ensure the steady-state operation and have excellent voltage and current sharing effects.
