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.
