ACEPACK power modules come in a variety of topologies and form factors to cover a wide range of automotive and industrial applications.

Our large product portfolio allows you to choose the right power converter topology for your application. For the automotive market, ACEPACK modules are tailored for main traction inverters, OBC, DC-DC and AC-DC converters, HVAC, and climate control. For industrial, the modules offer significant benefits in charging stations, solar inverters, UPS, and motor drive applications.

ACEPACK power modules are easy to implement thanks to their highly reliable and compact all-in-one design that ensures very high power density and reduced time to market.

The state-of-art power switches and other ACEPACK features ensure that our power modules offer the best compromise between conduction and switching energies to maximize the efficiency of any converter system, from a few kilowatts to hundreds of kilowatts.

The power modules are based on proven SiC MOSFET, IGBT, and diode technologies. Different pinout solutions are available to improve flexibility and the choice between Press-FIT and soldered pin connection facilitates assembly.

ACEPACK power modules are based on different layers, including a copper-ceramic-copper substrate that allows high flexibility in converter topologies and optimizes driving and power loops. The substrate ensures electrical insulation and guarantees very low thermal resistance.

ACEPACK power modules are part of the STPOWER family.

Product types

The product portfolio includes silicon IGBT and SiC MOSFET power modules with nominal voltage ratings from 650 up to 1200V, targeting a power range from tens to more than 300 kilowatts.

Thanks to the flexible, compact, and robust design, the ACEPACK power modules allow you to address different power converter stages for automotive and industrial applications.

The ACEPACK power module class consists of:

ACEPACK 1 and ACEPACK 2 power modules target power applications ranging from a few to hundreds of kilowatts and are available in several topologies implementing SiC MOSFET or IGBT-diode switch technologies. The IGBT and diode power modules are optimized for industrial motor control with CIB and sixpack topology at 650V and 1200V voltage ratings. The SiC MOSFET-based configurations are tailored for industrial applications such as energy generation and distribution, power supplies and converters like solar panels, charging stations, and UPS. Next generation ACEPACK 1 and 2 will be automotive-compliant solutions for high-power DC-DC converters, HVAC, and auxiliaries.

ACEPACK DRIVE is a very compact, direct-liquid-cooled, sixpack module family optimized for hybrid and electric vehicle traction inverters. These power modules implement power semiconductor switches based on the latest ST SiC technology guaranteeing unequaled R _DS(on), limited switching and conduction energies, and outstanding performance during synchronous rectification operation. Compared to standard market solutions, the module ensures superior system efficiency even during regenerative braking. The ACEPACK DRIVE family helps maximize the mileage of electric vehicles and allow smaller battery packs. The direct liquid-cooled base plate on ACEPACK DRIVE modules optimizes thermal performance and product lifetime is improved thanks to the sintering technology used for die attach and the AMB substrates. The ACEPACK DRIVE features a voltage rating from 750 V to 1200 V.

ACEPACK DMT-32 dual in-line, molded, through-hole, 32-pin power module is all-in-one solution tailored for BEV/HEV applications. It allows you to reduce your time-to-market for complex topologies with high power density and high efficiency. The DMT-32 offers fourpack, sixpack, and totem pole converter topologies featuring 1200V SiC MOSFETs. The state-of-the-art ST SiC technology and wide product portfolio ensure comprehensive power range and application coverage, including OBC, DC-DC converters, fluid pumps, and air conditioning.
