Abstract
A power converter section in which two serially connected snubber circuits, each formed by an asymmetrical element, such as a Zenner diode and a capacitor in series, and an auxiliary snubber circuit including a third capacitor coupled across parts of the first two snubber circuits, is disclosed. The described power converter section reduces the number of components and cost necessary for increasing surge voltage suppression.
