Analysis of Parasitic Resonance for High Switching-frequency Power Converters

In this thesis, analysis of parasitic resonance for high-switching converter is proposed. Parasitic components are analyzed and the way to reduced parasitic components is discussed. Also the RLC resonant model is formed, and lessen the parasitic components to reduce the effect caused by overshoot. In this thesis, parasitic components are focused on parasitic inductor. The formula of inductor and GMD method is combined to calculated the complex layout parasitic inductor, and the results are verified by both simulation and experiment. The RLC resonant is analyzed and modeled with parasitic components, and verified by experiment. The layout optimization strategy is proposed, both power stage and driver circuit, and RLC model is formed and verified by experiments.
