Chandler, Arizona, December 8, 2021 (Global News Agency) — Electric vehicles and renewable energy systems require power management solutions to improve performance and cost efficiency, and accelerate development time. To meet these requirements, Microchip Technology Inc. (Nasdaq: MCHP) today announced a collaboration with Mersen to develop its 150 kilovolt-ampere (kVA) three-phase silicon carbide power stack reference design. Mersen is a global supplier of power management solutions for many industries including electric vehicles 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 separate procurement, testing and certification. The power stack reference design includes Microchip's silicon carbide power modules and digital gate drivers, and Mersen's bus bars, fuses, capacitors, and thermal management, which are optimized 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 quickly develop high-voltage systems using pre-designed kits for their applications, reducing time to market by up to six months.
"Microchip customers will benefit from our cooperation with Mersen to provide silicon carbide MOSFET and digital gate driver solutions," said Leon Gross, vice president of Microchip's discrete products business unit. "When power inverter designers can purchase a proven solution, they can avoid purchasing individual parts and reduce risk through reliability-this helps avoid downtime. Designers now have an all-in-one evaluation system ."
The power stack reference design provides a power density of 16 kilowatts per liter (kW/l) and a Tj up to 130°C, a peak efficiency of 98%, and a switching frequency of up to 20 kHz (kHz). This reference design utilizes Microchip's rugged silicon carbide MOSFET and AgileSwitch family of configurable digital gate drivers, enabling engineers to choose from 700V and 1200V options at currents up to 750A. Microchip also offers module structure options, including substrate materials, direct bond copper (DBC) ceramic materials, and chip mounting methods.
Dr. Philippe Roussel, Vice President of Global Strategy, said: “Given the availability of highly robust silicon carbide MOSFETs and compatible digital gate drivers from a single source, we have worked closely with Microchip to design and develop this silicon carbide power stack reference design Mersen marketing Executive experts. "So, relying on our highly reliable series of busbars, capacitors, fuses and cooling systems, we can prove our ability to optimize any inverter topology for our customers. The versatile Microchip silicon carbide series also allows us to extend these main specifications to higher voltages, currents and switching frequencies to meet the operating point requirements of each customer. "
In addition to the products in the Mersen power stack reference design, Microchip is also a supplier of other silicon carbide power solutions, including 650V to 1700V MOSFET and Schottky barrier diode series, providing bare chips and various discrete and multi-chip module packages .
Microchip combines in-house silicon carbide chip production with its low-inductance power packaging and digital gate drivers, enabling designers to manufacture efficient, compact and reliable end products. These devices are perfectly matched with a comprehensive portfolio of microcontrollers (MCU), analog and MCU peripherals, as well as communications, wireless and security technologies, and provide system designers with proven overall system solutions for many applications.
The development tool Microchip’s AgileSwitch 2ASC-12A1HP 1200V dual-channel digital gate driver uses Augmented Switching™ technology, which is production-certified and fully configurable. Microchip's Intelligent Configuration Tool (ICT) supports the AgileSwitch 2ASC-12A1HP gate driver and the next-generation 2ASC-12A2HP. This interface allows users to configure gate driver parameters, including gate switch configuration files, system key monitors, and controller interface settings. ICT can be downloaded for free, which can save development time.
