Abstract
A method for operating a resonant converter in a burst mode includes determining the polarity of a transformer voltage across a secondary winding of a transformer. The method includes determining, from the polarity of the transformer voltage, on/off states of first and second transistors coupled to the secondary winding of the transformer. If the transformer voltage has a first polarity, the method includes commencing a burst period by alternately turning on/off high-side and low-side transistors electrically connected to a primary winding of the transformer.
