Analysis and design of a half-bridge parallel resonant converter operating above resonance

Young-Goo Kang; Anand K. Upadhyay; Dennis L. Stephens

A half-bridge parallel resonant converter (PRC) operating above resonance is analyzed in detail to provide a more straightforward and easy-to-use design tool. Closed-form solutions for the PRC are derived under steady-state conditions. Resonant component selection criteria is provided. Various design parameters derived from the results of the analysis are presented in the form of normalized design graphs to directly determine the component ratings. Using these design graphs, a step-by-step design procedure for a 100 kHz, 150 W multioutput switching power supply is given and implemented for verification of theoretical results.<<ETX>>
