ABSTRACT:
A resonant switching power supply has a zero voltage and zero current switch feature which can be operated in a half-bridge or a full-bridge scheme. This enables power consumption to be reduced and electromagnetic radiation to be minimized, and provides for low cost and convenient manufacture, in mass production. The power supply is not influenced by parasitic capacitance and leak inductance. The resonant switching power supply is disclosed in several different embodiments.
