1. A resonant power converter with AC full-wave primary-side resonance and zero-current switching adapted to convert power from an input DC voltage source to a DC terminal output load comprising:

  • an input stage configured to receive a first power signal from a DC input source;

    an AC full-wave magnetic interface configured to receive a second power signal from said input stage;

    an output stage configured to impose an output signal across a load by receiving said second power signal from said magnetic interface; and

    wherein said input stage includes a zero-current switch topology comprising a resonant capacitor, a resonant inductor and a unidirectional conducting device with a switching element arranged in series within said zero-current switch.
