1. A method of isolating a power supply circuit comprising:
providing a power source;
providing an inductor in series with a switching transistor connected to the power source; a pair of isolation capacitors connected across the switching transistor;
providing a load connected to the isolation capacitors;
having the isolation capacitors isolate the load from low frequency energy from the power source;
providing a resonance circuit; and
having the resonant circuit amplify resonant ringing.
