Abstract
The input direct current used to build up the electromagnetic field surrounding the windings of a flyback transformer is converted by direct transformer action to current for replenishing charge in a first capacitor. Flyback current from the flyback transformer is used to replenish charge in a second capacitor. The sum of the voltages across the capacitors is supplied as converted energy to a load. In accordance with the invention, ripple in this output voltage is suppressed by proportioning the capacitances of the first and second capacitors to equal a nominal value of the ratio of the durations of the time intervals where direct transformer action obtains to the durations of the flyback intervals.
