Abstract :
This paper presents a novel synchronous control strategy for the post buck converters directly cascading a LLC-SRC (series resonant converter) half-bridge converter, which can eliminate the input filter needed by general buck converters and decrease the ripple current flowing through the output capacitor of the front-end converter, thus leading to high overall efficiency and low cost. The separate control strategy of each post buck converter makes the standardized and modular design possible.
