Abstract:Input-series output-parallel converter is suitable for the high input voltage and output current DC-DC conversion application, but the structure brings the problem about input voltage sharing and output current sharing. The paper analyses the conditions of output current sharing deeply and indicates that the condition is system stability. Subsequently, the condition of system stability derived from small-signal model of the system, and the voltage feed-forward control strategy is proposed. Finally, the paper verifies correctness of the control strategy through Matlab simulation and experiment.
