A compact high voltage microsecond pulse power supply and its discharge application

To meet the requirement of some actual application experiments, a kind of high voltage microsecond pulse generator is developed. The output voltage amplitude is up to 30 kV with a minimum rise time of 300 ns and a pulse duration of 0.5 s. Some tests show that the output characteristics of the generator are determined by the load, and the input voltage and trigger pulse width can change the output pulse. Experiments by a point-to-point gas discharge are used to show the characteristics, the discharge modes can be changed by adjusting the pulse frequency and gap spacing. Different discharge modes can be distinguished by studying the variation of the pulse output with the load. Finally, the generator is successfully used for the excitation of atmospheric-pressure dielectric barrier discharge.
