Abstract
A DC-to-DC chopper circuit has a first switch that is selectively actuated to supply load current to a regulated bus and bus voltage to a resonating circuit which increases the applied voltage to approximately twice the value of the bus voltage, and a second switch selectively actuated so that the current on the bus flows through the resonating circuit discharging the increased voltage stored therein to zero whereupon a freewheeling circuit permits the established current to freewheel until the next chopper cycle.
