Microchip collaborates with Mersen for SiC reference design
Electric vehicle (EV), commercial transportation, renewable energy and storage system designers can reduce time to market by up to six months, claims Microchip, using the 150kVA, three-phase SiC stack. There are also performance benefits and cost savings, adds the company.

Mersen provides power management for multiple industrial markets, including e-mobility and renewable energy systems.

Mersen’s three-phase SiC Power Stack reference design is compact and negates the need for individual device sourcing, testing and qualification. It includes Microchip’s 1200V MSCSM120AM042CD3AG silicon carbide MOSFET and AgileSwitch 2ASC-12A1HP digital gate driver with Mersen’s bus bar, fuses, capacitors and thermal management.  Engineers can reduce time to market by up to six months using a kit pre-designed for specific applications.

Leon Gross, vice president of Microchip’s discrete product business unit, said: “When power inverter designers can source a proven solution, they can avoid sourcing individual parts and reduce risk through reliability – and that helps avoid downtime. Designers now have an all-in-one evaluation system.”

The Power Stack Reference Design provides 16kW/litre of power density and up to 130°C Tj, peak efficiency at 98%, with up to 20kHz switching frequency. The rugged SiC MOSFETs and AgileSwitch configurable digital gate drivers allows engineers to select from 700V and 1200V options in currents up to 750A. Microchip offers a choice of module construction including baseplate material, direct bonding copper (DBC) ceramic material and die attach method.

Philippe Roussel, PhD, vice president, global strategic marketing executive expert at Mersen said the company can demonstrate its ability to optimise “any inverter topologies” and that the combination of its bus bars, capacitors, fuses and cooling systems with Microchip’s SiC devices allows Mersen the capacity to extend “primary specifications to higher voltage, current and switching frequency to meet every customer’s operating point needs”.

Microchip’s AgileSwitch 2ASC-12A1HP 1200V dual-channel digital gate driver with Augmented Switching technology is production-qualified and fully configurable. The AgileSwitch 2ASC-12A1HP gate driver and 2ASC-12A2HP are supported by Microchip’s Intelligent Configuration Tool (ICT), an interface allowing users to configure gate driver parameters including the gate switching profiles, system critical monitors and controller interface settings. The ICT is available as a free-of-charge download.
