Abstract
A controller for controlling a resonant switching dc to dc converter. The controller has four output terminals, each of which is capable of switching one of four transistors in a bridge power stage in such a way as to accomplish zero-voltage resonant switching. The phase relationship between the switching of the four transistors of the bridge power stage which is adjustable from approximately zero to 180.degree., results in highly-efficient, pulse-width-modulation of the output power.
