摘要： 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.

摘要： 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.

摘要： A semiconductor power module includes a filter element made of a magnetic material that can be exchanged as required, while providing a package having a compact size. The power module can be used for a power conversion device for providing power conversion of DC power or AC power by switching a power semiconductor element, such as an IGBT. The filter element can be an annular magnetic member that rests around one or more terminals connected to the power semiconductor element. Noise current flowing through the terminals, when the power semiconductor element is switched, can be suppressed effectively with the annular magnetic member.
