Abstract
An LLC converter includes a switching stage including primary transistors, a resonant stage connected to the switching stage, a transformer including a primary winding connected to the resonant stage and a secondary winding coupled with the primary winding, a rectifying stage connected to the secondary winding of the transformer and providing an output voltage of the LLC converter, and a controller configured and/or programmed to, during start-up, control the output voltage by switching the primary transistors based on a first reference voltage that exponentially increases during start-up and a second reference voltage that is based on a resonant current of the resonant stage.
