Abstract
A snubber network of high energy efficiency for use with power conversion semiconductors is described. Asymmetrical semiconductor elements are used to reduce and dissipate voltage spikes induced by stray inductance during turn-off of power semiconductors. A space efficient assembly using the described snubber network containing asymmetrical semiconductor elements and an external snubber capacitor is also described.
