The converter includes a primary circuit, transformer and secondary circuit. The primary circuit takes the form of a “full bridge converter,” a “push-pull converter,” or an “L-type converter.”. The primary circuit may include a dissipator such as a snubber circuit or small buck converter. A secondary side of the transformer is momentarily shorted by the secondary circuit by, for example, turning on at least two switches in the secondary circuit simultaneously for a minimal calibratable period when a pair of primary circuit controllers turn off to protect the primary circuit switches from voltage spikes during switching conditions.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/56/765/068/0.pdf10118659363/17363/56.2363/56.5H02M1/34H02M3/33584H02M3/33592H02M3/337H02M2001/342H02M2001/348Y02B70/1475Y02B70/14916876556
