<p>A regenerative drive circuit for driving the gate of a power MOSFET of a switched mode power converter includes a pair of MOSFETS connected in series with a pair of coupled inductors L 1 , L 2 and L 3 , L 4 which are connected in parallel. A first blocking capacitor is connected in series with inductor L 3 and a second blocking capacitor is connected in series with inductor L 4 . A positive voltage source is provided to one MOSFET and a negative voltage source is provided to the other MOSFET, and the gate drive circuit provides energy recover.</p> |
