800-Volt Silicon Carbide Inverter

Our 800-Volt Silicon Carbide Inverter for Electrified Vehicles uses an innovative, double-side cooled silicon carbide (SiC) based power switch that delivers the higher power densities and efficiencies needed to extend battery range and performance, and reduce costs.

Its patented capabilities give manufacturers the propulsion system design flexibility and performance they need to drive consumer demand – and the vehicle mix and volumes required to meet increasing emissions regulations.

The inverter’s SiC technology can help extend electric vehicle range by c.5% and enables faster charging times at 800-volts when compared to today’s 400-volt systems.

Silicon Carbide Performance Inverter Platform

Compact silicon carbide MOSFET performance inverter platform (SiC-PP).

Lighter, more efficient, and more compact.

Thanks to the advanced architecture of the SiC-PP, it is possible to meet a wide range of performance and use cases, from ground transportation to aviation applications. The advantages of SiC semiconductors have been optimally exploited to achieve the best balance of performance, weight and cost.

850-Volt Multi Level High Speed Inverter

850-Volt Multi Level High Speed Inverter

High speed kept under control – with low system costs.

Thanks to BorgWarner’s multilevel technology, motor and generator speeds of up to 180,000 rpm can be kept safely under control. The control technology and the high PWM frequencies achieved lead to significant rotor losses in the electric machine, resulting in a significant reduction in system costs. MLI was developed for fuel cell air compressors and electric turbochargers.

BorgWarner’s MLI-technology makes the difference, because the high PWM frequency and the additional voltage level mean that lower pulsations of the magnetic field can be achieved, resulting in significantly lower rotor losses.

Combined Inverter & DC/DC Converters (CIDD)

Inverters and converters work together to manage a vehicle's electric drive and accessory systems. By combining both elements into one, compact component we're meeting manufacturer's demands.

Our CIDD range delivers maximum power density in a lighter, smaller, more cost-effective package. By eliminating extra DC/DC housing and liquid cooled connectors we've reduced the wire cabling between boxes – which increases reliability and saves you time and costs.
