Abstract

This paper shows that the hybrid bridge resonant converter which is based on the traditional LLC resonant converter, use DSP to toggle between the full bridge mode and the half bridge mode. So the input voltage range is enlarged, and in the high voltage range, the working efficiency is increased by 3%. The switching process between the full bridge mode and the half bridge mode could be made a smooth transition by the PI value setted control strategy.
