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 T1A coupled to a voltage source and a switch T3A coupled to the switch T1A. The primary side of the second stage includes a switch T2A coupled to the switch T3A and a switch T4A coupled to the switch T3A and 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.
