Abstract

Abstract

The resonant circuit can realize soft switching and reduce switching loss, and is widely used in the field of power electronics. The resonant circuit can generate pulse-shaped voltage in a specific mode. Compared with other pulse generator topologies, it has the advantages of fewer switches, lower switching loss and lower electromagnetic interference (EMI). The resonant circuit usually requires a half-bridge or full-bridge converter to generate a square wave excitation. This paper proposes a pulse circuit that combines a pulse transformer and a single-switch resonant circuit. The main circuit only needs to use a semiconductor switch to produce high voltage pulses via the resonant circuit and the pulse trausformer on the secondary side with zero current switching (ZCS). This paper theoretically analyzes the working process of the circuit, and sets up prototype to carry out the load experiment. The test results show that a sinusoidal pulse voltage with a frequency of 10−20 kHz and an amplitude of 5−10 kV is realized on a dielectric barrier discharge (DBD) load. The pulse circuit has simple structure, stable operation and low cost.
