Patent ID: 7362594

Claim:
An adaptive resonant power converter comprising: a gate drive transformer comprising a first sensing primary winding, a first secondary winding, and a second secondary winding; a first MOSFET having a gate connected to said first secondary winding; a second MOSFET having a gate connected to said second secondary winding; said first and second MOSFETS connected to each other in series across a direct current input source and forming a common MOSFET node therebetween at said first MOSFET source and said second MOSFET drain; a main transformer comprising a primary winding and a first resonant output winding; an input capacitor having a first capacitor node connected to said first MOSFET drain and a second capacitor node connected to said main transformer primary winding; said main transformer primary winding connected between said common MOSFET node and said second capacitor node; and wherein a first tap of said first resonant output winding is connected to a first tap of said first sensing primary winding, a second tap of said first resonant output winding is connected to a first load terminal of a first load, and a second tap of said first sensing primary winding is connected to a second load terminal of said first load.
