Abstract

Envelope modeling is an efficient way to obtain large-signal amplitude and phase dynamics of fast-varying sinusoidal signals, required for e.g. resonant frequency tracking of power converters. In addition, the method eliminates fast-varying parameters from the model, resulting in reduced simulation time and memory requirements. The paper focuses on envelope modeling capacitor-powered resonant inverter feeding a time-varying series RLC load in burst mode so that DC-link capacitor voltage variation is considered as state variable and must then be combined with the dynamics of AC-side variables. Simulation results are presented to validate the suggested analysis method.
