为了获得10 kV以上的高压窄脉冲输出，采用高压脉冲Transformer和LCC逆变充电器设计了一种混合储能的高重复频率脉冲电源，在不使用高频Transformer的情况下，LCC逆变器的整流输出直接对原边电容充电，从电容充电等效于电压的角度分析了逆变器的工作原理给出了各参数的选择原则和计算方法，分析了电容器对脉冲变压器Transformer的充放电过程，指出通过关断最大放电电流，可在负载上获得高压窄脉冲，实验结果表明，该电源可实现上升时间为1.0 μs的脉冲电压输出，30 kV振幅和1.5 μs脉宽（90%幅值），重复频率可达2.5kHz以上，并可实现上升时间8ns，幅值4800A的脉冲电流输出，从而使中间储能电容可通过充电器快速充电，且成本低，结构简单、紧凑，可用于废气处理，也可用于需要数万伏高压窄脉冲输出的场合。
In order to obtain a high-voltage narrow pulse output of more than 10 kV,a high repetition rate pulsed power supply with hybrid energy storage is designed using high-voltage pulse transformer and LCC inverter charger.Without the high-frequency transformer,the primary capacitor is charged directly by rectifying output of the LCC inverter.The working principle of the inverter is analyzed in the way of charging capacitor being equivalent to voltage source.The selection principles of parameters and their calculation methods are given.The analysis of the processes of capacitor charging and discharging to the pulse transformer indicates that high-voltage narrow pulse can be obtained on the load by switching off the maximum discharging current.The experimental results show that the power source can achieve the pulse voltage output with 1.0 μs rising time,30 kV amplitude and 1.5 μs pulse width(90% amplitude),and repetition rate can reach more than 2.5 kHz.Also,the power source can achieve the pulse current output with 8ns rising time and 4 800 A amplitude.Thus the middle storage capacitor can be charged quickly by the charger.The power source has low cost,simple and compactly integrated structure.It can be used for waste gas processing,and it can also be used in the situation requiring tens of thousands volts high-voltage narrow pulse output.
