Ringing and Voltage Overshoot Analysis of a Proposed DC/AC Converter

Abstract

This research presents a study of the ringing and voltage overshoot analysis of a proposed DC/AC converter. This overvoltage is generated due to the resonance between three passive components: transformer leakage inductances, switch capacitances, and wiring resistances. By applying simple RLC circuit equations, it proves possible to determine the analytic equations and reproduce the voltage across the switches to predict the overvoltage and resonance frequency. The circuit is built and tested experimentally to validate the theoretical concept.
