Hillcrest Energy (HEAT) has completed its 800-volt, 250-kilowatt Zero Voltage Switching (ZVS) traction inverter commercial prototype.

Through the material elimination of switching losses, the 800V, 250kW Hillcrest ZVS or soft switching capabilities traction inverter prototype can take advantage of higher operating frequencies at higher voltage and offer improved motor efficiency, performance, and reliability.

The Hillcrest ZVS inverter technology can be applied with batteries, electric motors, generators, fuel cells or virtually any other power source where power conversion is needed.

Enabling switching at higher frequencies with Hillcrest’s ZVS inverter technology can allow for much smaller capacitors in an inverter. With the Hillcrest ZVS inverter technology, these capacitors can be reduced by as much as half in size, offering a smaller, lighter inverter that can offer higher power densities than EV inverters currently on the market. This can all be compiled into better range, performance and/or gains in payload capacity as well as bill-of-material savings for manufacturers and motor efficiency improvements of up to 13 per cent.

Ari Berger, the company’s CTO, said that implementing their technology in these systems, expected to occur by Q2 2023, will mark another important milestone by transitioning the technology out of their lab and into real-world demonstrations of the Hillcrest ZVS inverter in commercial applications.

“We’ve validated our core technology and will continue working with Hercules Electric Mobility and a Tier 1 automotive supplier, our previously announced co-development partners, on integrating our ZVS traction inverter into their specific powertrain applications.”

Don Currie, Hillcrest’s CEO, added that in just one year, the company progressed from a 10-kilowatt proof of concept to a 250-kilowatt ZVS traction inverter commercial prototype.

“Add the incredible customer interest we’ve already received, highlighted by two announced MOUs, and I believe we are clearly demonstrating our ability to be at the forefront and deliver innovations that will advance power electronics for the next generation of mobility.”

Hillcrest Energy develops clean power conversion technologies and digital control systems for powertrains and grid-connected renewable energy systems.

Hillcrest Energy Technologies (HEAT) is up by 10 per cent, trading at $0.11 per share as of noon ET.
