Borg Warner is developing a Scalable Ultra Power-dense Extended Range (SUPER) inverter with the aid of a $4.97 million award from the U.S. Department of Energy (DOE). The project is one of 24 university and industry-led initiatives collectively awarded $60 million in an effort to reduce carbon dioxide emissions from the transportation sector.

The 39-month research effort will focus on engineering an advanced inverter that is smaller, more efficient and more cost-effective than those currently available. The device will be designed to enable 800 V electric Source: Borg WarnerSource: Borg Warnervehicles to meet or exceed the DOE target of 100 kW per liter of power density. Project plans also call for a design that allows high power density with power scaling between 100 kW and 300 kW and can be used either as a standalone device or integrated into a drive unit that includes a motor and gearbox.

Initial efforts will establish the concept for the silicon carbide-based inverter system, followed by the manufacture of critical components, including the power module and capacitor, and finalization of the design. Once the components and the SUPER inverter are validated, the researchers expect to take the technology from development to production relatively quickly.

Infineon Technologies Americas Corp., PolyCharge America, Inc., the U.S. National Renewable Energy Laboratory, Wolfspeed Inc. and Virginia Tech are also contributing to the SUPER inverter project.
