250kW 800V SiC EV traction inverter
The Hillcrest 250kW 800V SiC EV traction inverter leverages a new class of inverter technology that solves many common challenges faced by today’s EV powertrains. Lighter, more compact and more efficient than current inverters, our inverter technology enables reduced overall vehicle weight, increased payload and range capability and reduced heat production/loss, thereby optimizing battery and performance reliability.
Hillcrest EV Traction Inverter Differentiators
The Hillcrest high efficiency inverter is a new class of inverter technology that solves many common challenges faced by today’s electric power systems. Three key differentiators set the Hillcrest inverter technology apart:
First traction inverter to achieve inverter efficiency exceeding 99%.
Smaller + Lighter + More Powerful
The combined benefits of the Hillcrest inverter enable the smaller, lighter and more powerful capabilities required of next-generation EVs.
System Reliability + Performance
By eliminating inverter losses, the Hillcrest inverter reduces the thermal management needed across the entire powertrain system. This can generate substantial savings, reduce system complexity and improve system reliability by reducing stress on power devices.

System-wide Efficiency Gains
Hillcrest inverter technology eliminates the traditional design trade-offs faced across the power industry – deploying higher switching frequencies historically has meant a greater increase in losses (lower system efficiency, higher heat).
The Hillcrest inverter technology enables power applications to leverage higher switching frequencies AND realize improved traction motor performance and reliability AND operate at higher power levels without compromising efficiency.
At the intersection of range and cost considerations, the traction inverter remains the epicenter for innovations aimed at unlocking further EV efficiency and range gains.
By achieving highest inverter efficiency AND industry-leading power density, EV OEMs could replace many of their current design trade-offs with possible opportunities:
