Abstract
An apparatus includes first and second power converter stages, each stage having a primary side and a secondary side. The primary side of the first stage includes a switch Tcoupled to a voltage source and a switch Tcoupled to the switch T. The primary side of the second stage includes a switch Tcoupled to the switch Tand a switch Tcoupled to the switch Tand to the voltage source. The apparatus includes a control circuit to control an on/off time of the switches. The control circuit includes four gate driver controllers to control the on/off time of the switches and a current sharing control section to increase or decrease the on time of a switch based on a comparison of a current through one of multiple output inductors to an average current through the multiple output inductors.
