Abstract :
A half-bridge parallel resonant converter (PRC) is analyzed in detail for both continuous-conduction-mode and discontinuous-conduction-mode operations to provide more straightforward and easy-to-use design tools. Closed-form solutions are derived for the PRC operating under steady-state conditions. Theoretical results obtained are presented in the form of normalized design graphs. They could be directly utilized in designing a half-bridge PRC, having up to 2:1 input voltage variation. They do not necessitate converting the obtained ratings, depending on the input voltage and load variations, to check the worst case values. A design example of a 500 kHz 150 W offline switching power supply is given for both modes of operation, and it is implemented for experimental verification.<>
