STPOWER ACEPACK DRIVE Power modules based on our 3rd generation SiC MOSFETs

Combining the intrinsic features of Silicon Carbide technology with an optimized compact design and an internal layout able to minimize the stray inductance, the ACEPACK DRIVE power modules are ideal for HEV/EV traction inverters.

The new automotive-grade power module series features a very low RDS(on), limited switching losses and outstanding performance in synchronous rectification mode. Thanks to the 3rd generation SiC MOSFET technology, our latest ACEPACK DRIVE modules ensure increased efficiency and maximizing electric vehicles mileage range.

Furthermore, the very high-power density of the new ACEPACK modules minimizes system room occupation required by the market’s evolving needs.

ACEPACK DRIVE power modules offer optimal thermal performance thanks to their direct liquid-cooled baseplate and, at the same time, an enhanced lifetime thanks to the sintering technology used as die attach, combined with the AMB substrates.

The wide product portfolio available in short and long bus bar mounting options targets a power range from 180 to more than 300 kW.
