Microsecond electroporator optimization for parasitic load handling and damping

Abstract

During development of the pulsed power generators the o ccurrence of the parasitic elements in the circuit is inevitable, which leads to appearance of overvoltage, overcurrent and waveform distortions. This work is focused on the optimization of the microsecond electroporator to enable handling and damping of the parasitic loads. The optimization is based on a flexible PSPICE model of the electroporator, which is used for the compensation of the parasitic parameters. Based on the modelling results the parameters and the circuit elements for the device are selected. The compliance of the prototype’s experimental and the PSPICE simulated output pulses is analysed. The optimized circuit of the microsecond electroporator is designed. The system supports current handling up to 100 A and capable to generate up to 4 kV square wave pulses.
