摘　　要：高峰均比低频脉冲电流载荷影响航天器电源系统高效稳定运行,基于大容量储能电容阵的脉冲功率被动平抑技术极大增加航天器系统的体积重量。以降低航天器电源系统体积重量为目标,提出基于部分功率调控的脉冲功率平抑方法。通过将无源解耦电容分裂为有源电容与无源解耦电容串联,不仅为负载提供稳定的供电电压,而且大幅增加解耦电容电压波动范围、减小解耦电容体积重量。由于有源电容仅需提供部分脉冲负载功率,有效降低了脉冲功率主动平抑所需额外增加的功率电路容量、体积重量和损耗。文中详细分析所提脉冲平抑系统架构、电路实现及其控制方法,实验结果证明了所提方法的可行性和有效性。The high peak to average ratio low-frequency pulse current load affects the efficient and stable operation of spacecraft power system.The pulse power passive suppression technology based on a high-capacity energy storage capacitor array increases the volume and weight of the spacecraft system greatly.A pulse power stabilization method based on partial power regulation is proposed to reduce the volume and weight of spacecraft power supply systems.By splitting the passive decoupling capacitor into the active capacitor and passive decoupling capacitor in series,not only stable power supply voltage is provided for the load but also the voltage fluctuation range of the decoupling capacitor is greatly increased.Meanwhile,the volume and weight of the decoupling capacitor can be reduced.Since the active capacitor only needs to provide part of the pulse load power,it effectively reduces the additional power circuit capacity,volume weight,and loss required for active suppression of pulse power.The architecture,circuit implementation,and control method of the proposed pulse suppression system are analyzed in detail.The experimental results show that the proposed method is feasible and effective.
