Abstract

A compact pulsed high-voltage generator has been developed for applications in pulsed gas discharges. Its operation principle is based on inductive energy storage and it uses a static induction thyristor as the opening switch. It is capable of generating pulsed high voltage of ~15 kV with pulse width of ~200 ns for load resistance of 1 kOmega. This generator can be operated at repetition rate as high as 50 kHz if it is driven directly by 200 V power supply and is cooled by transformer oil. It can also be driven by a 12 V car battery through a chopper circuit, while operating at repetition rate of 2 kHz. In this case, an overall energy efficiency of ~40 % has been obtained.
