ABSTRACT:
Circulating current through a resonant tank circuit and inverter switches is reduced by feeding high frequency current back through a line inductor. A resonant load circuit is connected between an inverter output node and one of the terminals of the input rectifier circuit. A high frequency capacitor has one terminal connected to an AC-side terminal of the input rectifier circuit. The line inductor and the high frequency capacitor have values selected such that instantaneous high frequency capacitor current flow into that AC-side terminal has a greater magnitude than and polarity opposite to current through the line inductor into that AC-side terminal during a portion of every cycle of the high frequency voltage.
