基于平均值模型对感应子脉冲发电机电容器重频充电系统进行了研究。分析了次暂态磁链在充电过程中的变化规律，以及次暂态磁链的变化对充电性能的影响。仿真和计算结果表明，次暂态磁链在充电过程中逐渐变小。当充电时间与发电机的电磁时间常数相当时，充电过程中次暂态磁链下降会导致充电电压明显降低，因此必须考虑次暂态磁链变化的影响。进一步研究了具有恒流控制功能的励磁电源对充电过程中调节作用的影响，并指出为了降低发电机对绝缘性能的要求，在重频充放电脉冲模式下励磁电流应该采用逐渐上升的方式。

Based on the average value model, the capacitor repetitive charging system of pulsed homopolar inductor alternator is studied. The variation law of sub-transient flux linkage during the charging process is analyzed, as well as the impact of sub-transient flux linkage variation on charging performance. Simulation and calculation results show that the sub-transient flux linkage gradually decrease during the charging process. When the charging time is equivalent to the electromagnetic time constant of the generator, the decrease in the sub-transient flux linkage during the charging process leads to a significant decrease in the charging voltage, so the impact of the sub-transient flux linkage change must be considered. The impact of excitation power supply with constant current control function on the regulation during charging is further studied, and it is pointed out that in order to reduce the insulation requirements of the generator, a gradual rise of the excitation current in the repetitive charging and discharging pulse mode should be adopted.
