Analysis and Design of a High-Frequency Resonant Converter Using LCC-Type Commutation

The modeling, analysis, and design of a high-frequency resonant converter using an LCC-type commutation circuit is presented. Constant-current model and state-space approaches are used for the analysis. Closed-form solutions are derived for the inverter under steady-state conditions. Experimental results obtained from a prototype converter under different loading conditions are compared with the theory.
