A Solid-State Pulse Power Generator Employed Magnet Switch for Dielectric Barrier Discharge Applications Based on Resonance Charging Concept

Abstract

This paper presents a novel high voltage pulse power generator layout that is well suited to dielectric barrier discharge applications. To reach the higher gain, a push-pull circuit with a three-winding transformer is used on the charging side, along with quasi-resonant between the transformer leakage inductance and the capacitor on the high-voltage section. The primary side's two windings and two low voltage switches allow the gadget to generate either unipolar or bipolar high voltage exponential pulses from an approximately low DC source. Instead of a bidirectional switch, a magnet one is employed since it eliminates the concerns of series and parallel connections of semiconductor switches in high voltage side, resulting in a low degree of switching complexity. Hence, In addition to accomplishing the high gain objective, the effort focuses on lowering the number of circuit elements and control complexity in contrast to previous topologies. The generator operates in discontinuous conduction mode, which improves the system efficiency by allowing for the generation of full positive and/or negative waves while it also reduces the conduction losses. The operation phases of the pulse generator are detailed. It is found from the simulation results that the proposed pulse generator outperforms the previous structures in terms of control complexity, number of switches, and flexibility.
