Mersen beats next generation DOE power density targets through Stack Reference designs

150 kVA – 16kW/L SiC power stack for heavy-duty EV

Mersen partnered with AgileSwitch and FTCAP to develop two high performance 3-phase inverter power stack reference designs. The SiC MOSFET version uses Wolfspeed SiC modules to deliver 150 kVA at a power density of 16 kVA/l, exceeding the DOE’s 2020 roadmap for electric vehicle applications.

The IGBT version – designed in the frame of Infineon’s Industrial Power Partner Network – uses Infineon IGBT5 modules with .XT technology to deliver up to 500 kVA and is targeted at Electrical Energy Storage applications. This reference design achieves a power density of 25 kVA/L.

“Mersen, Infineon, AgileSwitch and FTCAP have gathered together the latest technical innovations that can be offered to our inverter manufacturer clients” stated Mr. Philippe Roussel Ph.D, VP Strategic Marketing at Mersen.

Mersen claims this integrated architecture approach allows inverter designers to save time and confusion in selecting individual components with a solution that is optimally pre-designed for specific applications. Power semiconductor modules, busbar assemblies, cooling, gate drivers and capacitors are optimally integrated together in one step to address the electrical, mechanical and thermal challenges of the system.

Reference designs can be supported by purchasing individual components and, in addition, Mersen can provide assembly services.
