Abstract
A circuit for providing dynamic output current sharing using average current mode control for active-reset and self-driven synchronous rectification with pre-bias startup and redundancy capabilities for power converters. The circuit communicates a secondary side feedback signal to a primary side via a bidirectional magnetic communicator that also provides a secondary voltage supply. Pre-bias startup is achieved by detection of the output current direction and controlling the gate signals of synchronous rectifiers. The circuit permits dynamic current sharing via a single-control signal and automatic master converter selection and promotion.
