Resonant converter designs applying computation algorithms of bifurcation values <Abstract> This paper proposes a design method of resonant converters applying computation algorithm of bifurcation values. As a design example, the phase-controlled resonant dc-dc converter with the class-D Zero-Voltage Switching (ZVS) inverter and the class-E rectifier is designed. By drawing the ZVS region on the parameter space, it is possible to obtain the proper component values for satisfying the ZVS condition at any phase shifts. The validity of the design method was confirmed from the quantitative agreements with PSpice-simulation and experimental results. |
