Abstract :
A high-speed methodology for analysing fourth-order LLCC resonant converters is presented. Formula-based predictions of output voltage and, importantly, estimates of voltage and current stresses on resonant components, are derived. Comparison of predictions with those from SPICE demonstrate a high degree of correlation whilst requiring only 1/10,000th of the computation time.
