Abstract
A resonant converter highly improves light load efficiency. The resonant converter blocks control signals which are used to control power switches in an input power stage and an output stage in light load condition until an output voltage drops to a preset value. The input power stage and the output stage are coupled by way of a resonant net and a transformer.
