Power Modules offer Superior Efficiency for PV and UPS Systems

Vincotech has unveiled the new flow3xMNPC 1 modules featuring three mixed-voltage NPCs in a single flow 1 housing. Developed for 1200-V solar three-phase inverter applications, they enable engineers to design compact, space-saving inverters with excellent efficiency ratings. The flow3xMNPC 1 module performs remarkably well, achieving around 98.7% efficiency in typical 16-kHz solar applications. Measuring 82 mm by 38 mm and 12 or 17 mm in height, these modules support three phases in one flow 1 housing. They are equipped with 1200 V IGBT4 HS3s (high speed) in the half bridge and 600 V IGBT3s with low saturation voltage and ultra fast Stealth™ diodes in the neutral path.

The new modules are actually dual-module solutions that combine a booster and three-phase inverter, which makes them a superior option for smaller inverters where space is limited and a small footprint is necessary. In addition, rather than using a common emitter that requires seven power supplies, the M74x topology features a common collector configuration, thereby reducing the number of power supplies for the gate driver to five.

Models and ratings include: the 10-FY12M3A025SH-M746F08 rated for 3 x 25A for a total power-handling capability of 12 kW in a 12 mm housing; the 10-F112M3A025SH-M746F09 rated for 3 x 25A for a total power-handling capability of 12 kW in a 17 mm housing; the 10-FY12M3A040SH-M749F08 rated for 3 x 40A for a total power-handling capability of 18 kW in a 12 mm housing; and the 10-F112M3A040SH-M749F09 rated for 3 x 40A for a total power-handling capability of 18 kW in a 17 mm housing.

The IGBTs in all modules are equipped Kelvin Emitters to boost switching performance and an NTC for measuring temperature. The VincotechISE simulation tool provides flow3xMNPC 1 simulation models. The modules are in production and samples are available via the standard sales channels. Press-fit versions are also available on request.
