Microchip to Provide Silicon Carbide MOSFETs and Digital Gate Drivers for Mersen’s SiC Power Stack Reference Design

Electric vehicle, commercial transportation, renewable energy and storage system designers can benefit from silicon carbide stack solution that drives performance and cost efficiencies and accelerates time to market by up to six months

CHANDLER, Ariz., Dec. 08, 2021 (GLOBE NEWSWIRE) -- E-mobility and renewable energy systems require power management solutions that drive performance and cost efficiencies in addition to speeding up development time. To keep pace with these requirements, Microchip Technology Inc. (Nasdaq: MCHP) today announced the collaboration with Mersen on their 150 kilovolt-ampere (kVA) three-phase silicon carbide Power Stack Reference Design. Mersen is a global provider of power management solutions for numerous industrial sectors including e-mobility and energy storage.

Mersen’s three-phase SiC Power Stack Reference Design provides system designers with a complete, compact, high-power silicon carbide solution without the need for individual device sourcing, testing and qualification. The Power Stack Reference Design includes Microchip’s silicon carbide power modules and digital gate drivers and Mersen’s bus bar, fuses, capacitors and thermal management, optimally designed together in a single high-performance stack reference design. With Microchip’s 1200V MSCSM120AM042CD3AG silicon carbide MOSFET and AgileSwitch 2ASC-12A1HP digital gate driver, the Power Stack Reference Design enables engineers to rapidly develop high voltage systems using kits predesigned for their applications – reducing time to market by up to six months.

“Microchip customers will benefit from our collaboration with Mersen to provide silicon carbide MOSFETs and digital gate driver solutions,” said Leon Gross, vice president of Microchip’s discrete product business unit. “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 16 kilowatts per liter (kW/l) of power density and up to 130°C T_j, peak efficiency at 98%, with up to 20 kilohertz (kHz) switching frequency. Utilizing Microchip’s rugged silicon carbide MOSFETs and AgileSwitch family of configurable digital gate drivers, the reference design enables engineers to select from 700V and 1200V options in currents up to 750A. Microchip also provides a choice in module construction including baseplate material, Direct Bonding Copper (DBC) ceramic material and die attach method.
