Nanosecond high voltage pulse generator for biological and biomedical application

Benefit from photoconductive semiconductor switches (PCSS's) fast response, high power, high stability and long lifetime properties, design and operation of high voltage nanosecond power generator based on PCSS for biological and biomedical application is presented. The generator comprises of pulse power source, photoelectric synchronization control apparatus, PCSS based on Blumlein transforming line and laser diode circuit. It produces 1 kHz repetition frequency rate (RFR), 1-5 ns pulse duration, 1-10 kV amplitude pulses, which can be used in cancer treatment.
