Abstract
A power system includes power conversion circuitry that has a first switch and a second switch on either side of a transformer. The system also includes gate driver circuitry that operates the first switch and the second switch. Power transfer in a normal operating mode from a primary side to secondary side of the DC-DC power conversion circuitry is controlled by operating the first switch. The system can recover voltage from the secondary side to the primary side by reversing a direction of power transfer when a voltage on the primary side of the DC-DC power conversion circuitry is less than an operating voltage of the gate driver circuitry. The system can resume the normal operating mode when the voltage on the primary is greater than the operating voltage of the gate driver circuitry.
