Isolated power converter

A system comprising:

• a first load terminal for connection to a power source;
• a second load terminal connected to a load;
• and
• an isolated power converter circuit comprising:
• a transformer comprising a primary winding and a secondary winding, wherein an intermediate tap of the primary winding is coupled to a source;
• a first power amplifier coupled to a first end of the primary winding;
• a second power amplifier coupled to a second end of the primary winding;
• a first rectifier coupled to a first end of the secondary winding;
• and
• a second rectifier coupled to a second end of the secondary winding,
• wherein a capacitance provided at the first power amplifier and the second power amplifier, and an inductance provided by the transformer forms a primary resonant tank,
• wherein a capacitance provided at the first rectifier and the second rectifier, and an inductance provided by the transformer forms a secondary resonant tank, and
• wherein the first load terminal is coupled to the source of the isolated power converter circuit, and the second load terminal is coupled to the first rectifier and the second rectifier of the isolated power converter circuit.

A method for transferring power from a first side of an isolation transformer to a second side of the isolation transformer, the method comprising:

• providing power to an intermediate tap of a primary winding on the first side of the isolation transformer;
• generating a first resonance in the primary winding using a first power amplifier coupled to a first end of the primary winding and a second power amplifier coupled to a second end of the primary winding;
• rectifying a current caused in a secondary winding on the second side of the isolation transformer that is inductively coupled to the primary winding using a first rectifier coupled to a first end of the secondary winding and a second rectifier coupled to a second end of the secondary winding;
• and
• providing the rectified current to an output.
