With the development of space technology, satellite power supply system has higher requirements for circuit reliability, system efficiency and power density. In order to enhance the reliability of the circuit and improve the efficiency of the system, a maximum power point tracking (MPPT) circuit combined with shunt technology is proposed in this paper. When the circuit works at high power, it is in MPPT mode. With the reduction of power, the circuit will enter the shunt mode. In this paper, the principle of circuit mode switching is described in detail, and the feasibility of the control strategy is verified by simulation and experiment.
