Abstract Pulsed power technology has wide application in many fields, and higher requirements are put forward for the output parameters of pulse generator, including pulse voltage, pulse current, pulse width, repetition frequency and so on. In this paper, a novel scheme of adjustable polarity pulse generator topology based on induction isolation is proposed for the application of biomedical effect induced by pulsed electric field. Each module consists of a capacitor, two switches and an isolation transformer. The generator can output bipolar pulses by controlling the operating sequence of the switches, and the isolated transformer can isolate the potential changes at the same time. The results show that the basic principle of the pulse generator is still “parallel charging, serial discharge”. The generator can output bipolar rectangular pulse, and the pulse polarity, width and amplitude can be adjusted flexibly. The developed inductive isolation pulse generator can output a polarity adjustable pulse with an amplitude of ±6kV, a pulse width of 200~1 000ns and a rising edge of 10ns. In addition, the modular design can achieve higher parameter pulse by increasing the number of modules.

Key words： Pulsed power technology inductive isolation pulse generator bipolar pulse modular
