Abstract :
Two resonant DC-DC converters are presented where an LC tank is switched by an inverter. One of the presented topologies is buck-boost and the other one is inverting-buck converter. Few numbers of elements are employed, turn-on and turn-off ZCS conditions are provided for all active elements, energy circulation is reduced, and, power transferring is automatically stopped at output short-circuited. Experimental results from a 200W laboratory prototype confirm the presented theoretical analysis.
