A suppression methodology based on the high voltage energy storage system and bidirectional energy conversion is proposed in this paper to solve the stability problem caused by the transient power demand of the radar/direct energy weapon and the bidirectional power flow of four-quadrant electric actuator. Firstly, a bidirectional energy control topology based on high-voltage battery and bidi-rectional power conversion is proposed, which uses the instantaneous charging and discharging of high-voltage battery to cut peaks and fill valleys to achieve the bidirectional transient power control. Secondly, a comprehensive power supply management strategy based on bus voltage-load current and battery SOC is proposed to realize rapid detection of system load disturbance and fast config-uration of power supply mode. Thirdly, a voltage stabilizing control method based on differential tracker and load current feedfor-ward is proposed to improve the voltage performance of the converter under various load. The simulation and experimental results show that the proposed method can effectively suppress the voltage fluctuation caused by high-power bidirectional transient load disturbance, and improve the robustness and quality of aerospace HVDC power supply system.
