Abstract Because of the high input voltage and high rated power, the DC-DC converter in the auxiliary power supply system of subway is not easy to match the appropriate switching devices. In order to reduce the voltage and current stress of switching devices, Input-series Output-parallel (ISOP) structure is used. In this paper, the principle of voltage sharing and current sharing of ISOP converter is analyzed. The mathematical model and the controller of the converter is derived. Then the common duty control mode is studied, which verifies the rationality of the controller design. In the PSIM simulation, it is verified that the interlace control method can reduce the output current ripple and the filter capacitance to some extent. In order to reliably evaluate the performance and life of the system, an improved interlace control method to control the output current ripple within 5% is proposed. Simulation by Matlab establishes the effectiveness of this approach. Finally, the test of single-module rated-power at 40kW condition of ISOP system is established, which verifies the system output stability and dynamic and static performance. On this basis, the hardware experimental platform of ISOP system was built, and the debugging of low-power experiment was carried out, which confirmed the correctness of the equalization current sharing control method.
