Abstract:
A power supply comprising:a. a boost type pre-regulator having a pre-regulator input voltage and a pre-regulator output voltage and configured to perform an adaptive conversion on said pre-regulator input voltage, b. a base-sub half-bridge series resonant converter unit that includes a base converter and a sub converter, said unit connected to said boost type pre-regulator through a parallel connection of each of said base and sub converters, said base-sub converter unit receiving as input said pre-regulator output voltage, and configured to provide a phase shifted combined output, and c. control means for controlling said pre-regulator and said base-sub half-bridge series resonant converter unit, whereby said adaptive conversion by said pre-regulator, combined with said phase shifted combined output of said base-sub half-bridge series resonant converter unit, provide a highly efficient power conversion by the power supply.
