Active surge voltage clamped 600 A IPM for high power application

A new intelligent power module (IPM), rated 600 A and having an over-voltage protection function, which suits 1500 V DC to 2000 V DC 3 level inverter application, has been developed. In addition, the device promises to provide numerous other merits in the high power application fields. Most important of which is its ability to drastically reduce overall size and cost, including those of snubber components, of conventional systems based on existing power devices ( e.g. GTO thyristor, transistor module, IGBT module, etc.).
