Practical design methodologies for load resonant converters operating above resonance

Practical design techniques for load resonant power converters operating above resonance are presented. The design procedures use a sinewave approximation for the waveforms (i.e., only the fundamental components are considered). This in turn allows simple analyses of the converters based on AC complex analysis. Based on these analyses, design procedures are developed for the series, parallel, and series/parallel converters. The procedures allow the components to be selected and stresses to be determined rapidly using tools familiar to design engineers. The procedures are meant to allow the engineer to trade-off and arrive at initial design rapidly. These can be verified and fine-tuned using simulation and more detailed analyses if desired. A design example is given
