As an energy manager for spacecraft power supply systems, the combined non-isolated three-port converter (TPC) can transfer and transform the electric energy between the three power ports of solar photovoltaic, battery and load, showing advantages of high-power density, high conversion efficiency, easy system construction and easy on-orbit maintenance. The combined non-isolated TPC is stacked with an interleaved bidirectional Buck/Boost converter and a semi-active full-bridge rectifier to realize the single-stage power conversion between any two ports, and the independent power control of the two ports is achieved by the pulse width modulation and phase-shift modulation strategies. The working principle, modulation strategy and control strategy for TPC were analyzed in detail, the corresponding design considerations were proposed, and its performance was further evaluated by experimental results.
