IRVINE, Calif., May 28, 2009 (GLOBE NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC) a leading manufacturer of high performance analog mixed signal integrated circuits and high reliability semiconductors, has launched a new line of 20 standard three-level inverter power modules designed for solar converter applications.
"The introduction of these 20 three-level inverter power modules provides a wide range of solutions in terms of technologies and power ratings for solar inverter manufacturers," said Philippe Dupin, Director, Power Module Products, Power Products Group located in Bordeaux, France. "With very low profile and minimum parasitics these modules can enable very compact systems and the highest possible efficiencies, particularly if SiC diodes are used as replacements of FREDs," he added.
The standard modules are available in 600V and 1200V voltage for full IGBT configuration and in 600V and 900V for a mix of MOSFET and IGBT technology. Each module integrates a leg of the inverter such that three identical modules are used to achieve a 3-phase solar inverter. The modules are available in SP1, SP3 and SP6 packages.
Most of the 600V IGBT devices are offered with Trench and Field stop technology. Current specifications vary from 20A to 300A. Modules with current rating from 20A to 50A are integrated in SP1 and SP3 packages. Modules in SP1 packages offer a low-cost solution while equivalent modules in SP3 provide optional features such as an NTC thermistor for temperature monitoring and improved Kelvin connections for easier drive power devices.
The SP3 module range extends to 100A/600V and is also offered in 1200V with 60A current. At the high current end, standard modules with 150A, 200A and 300A currents are specified in the larger SP6 package with screw terminals.
Should the specified operating frequency be higher than 20 kHz, fast NPT IGBT modules are offered at 30A in SP1 and SP3 and 50A in SP3 to meet aggressive efficiency targets.

Standard modules can be provided with a mix of MOSFET devices to operate at high frequency and Trench and Field stop IGBTs for low conduction losses. Such topologies reach unbeatable efficiency goals. 600V Super junction transistors with Rdson of 99 mOhms, 70 mOhms and 45 mOhms are combined with respectively 30A, 50A and 75A Trench and Field Stop IGBTs. A module with 900V/120 mOhms Super Junction transistors combined with 1200V Trench IGBTs is available, should 600V devices prove insufficient in given systems. The modules exhibit two diodes across the output to meet requirements of reactive energy specifications.
