Square Voltage Power Supply Design Methodology for Dielectric Barrier Discharge Applications

This paper presents a design methodology for a square pulse voltage source used in dielectric barrier discharge applications. This methodology considers electrical aspects of the discharge such as the average power to be delivered and the duration of the current pulses to properly size the switches and perform the magnetic design of the step-up transformer, where parameters such as leakage inductance and parasitic capacitance are considered for its design. The methodology was validated with the design and implementation of a voltage power supply for an experimental nitrogen oxides treatment bench.
