Abstract
Switching between a dual switch topology and a bridge forward topology in a power converter includes: receiving an input voltage; providing, via the dual switch topology, an output voltage; determining that the input voltage falls below a first threshold; switching a path of the input voltage from the dual switch topology to the bridge forward topology; and providing, via the bridge forward topology, the output voltage.
