EV TRACTION INVERTER

At the intersection of range and cost, the traction inverter remains the epicenter for innovations aimed at unlocking further electric vehicle efficiency and range.

The Hillcrest ZVS Inverter Technology enables power applications to operate at higher power levels AND higher switching frequencies without compromising efficiency.

800V | 250 kW SiC EV Traction Inverter

Hillcrest has developed a proprietary implementation of Zero Voltage Switching (ZVS), a unique approach to soft-switching that, when combined with Hillcrest’s proprietary power electronics hardware and control firmware, achieves increased efficiency, performance and reliability in electric systems, such as electric vehicles.

The 800V | 250 kW EV SiC traction inverter leverages the Hillcrest ZVS Inverter Technology to solve many common challenges faced by today’s EV powertrains. Lighter, more compact and more efficient than current inverters, our ZVS Inverter Technology enables a reduction in overall vehicle weight, increased payload and/or range capability.
