Compact Power Modules for Solar Inverters

Tue, 08/28/2007 - 5:39am

ec79ps802a-LMicrosemi Corp. introduced its line of standard power modules for solar inverters in a space-saving compact SP3 package. The eight modules feature full bridge configurations combining low saturation “Trench & Field Stop” IGBT top switches with fast NPT IGBT bottom switches for unipolar switching. The top IGBTs operate at line frequency, while the bottom IGBTs switch at frequencies from 15 kHz to 50 kHz. Total losses are minimized, enabling maximum solar inverter efficiency. Diodes in the modules are matched to the power transistors for improved efficiency. High speed, soft recovery DQ Series diodes are designed in parallel with the top IGBTs to provide low recovery losses in combination with the bottom fast IGBTs.
