摘要：

This paper proposes a zero-voltage-switching（ZVS）three-port DC-DC converter（TPC）for spacecraft power system. For the TPC which integrates interleaved Buck/Boost converter（IBBC）with dual-active-bridge DC-DC converter（DAB），due to the ZVS range of MOSFET of the primary side is related to the power transmitted between the two ports of the primary side，in order to expand the ZVS range of the main switch，an auxiliary circuit based on coupled inductor is introduced into the topology. Compared with the traditional ZVS implementation method，this topology can prevent the notch on the current waveform of the battery port，which is beneficial to prolong the life of the battery in the spacecraft power system. The magnetic coupling inductor reduces the number of inductors，plays a filtering role，and provides the ZVS condition for the main switch. Finally，a TPC experimental prototype was built to verify the effectiveness of the topology structure and control strategy. © 2023 Science Press. All rights reserved.
