Hillcrest Energy Technologies Ltd. (CSE: HEAT) (OTCQB: HLRTF) Unveils Commercial Prototype of its ZVS Inverter Technology

  • Hillcrest Energy Technologies recently unveiled a commercial prototype of its 800-volt, 250-kilowatt Zero Voltage Switching (“ZVS”) traction inverter
  • The production of a commercial prototype comes only months after the company had published white papers, extolling the potential of their revolutionary technology
  • The inverter will be developed and integrated alongside Hillcrest’s partners, Hercules Electric Mobility as well as a separate Tier 1 automotive supplier
  • The company envisions its inverter technology being deployed with batteries, electric motors, generators, fuel cells and any other power source requiring power conversion

Hillcrest Energy Technologies (CSE: HEAT) (OTCQB: HLRTF), a clean technology company focused on developing transformative power conversion technologies, has recently announced the completion of its 800-volt, 250-kilowatt Zero Voltage Switching (“ZVS”) traction inverter commercial prototype. Whilst initially directed towards the electric vehicle industry, Hillcrests ZVS inverter technology can eventually be applied with batteries, electric motors, generators, fuel cells or virtually any other power source where power conversion is needed.

A key issue affecting both electric vehicle manufacturers as well as owners is efficiency losses emanating from a vehicle’s powertrain. A vital component in an EV powertrain, an inverter seeks to convert DC charge from the battery to AC to drive the electric. The more efficient the inverter is, the more efficient the vehicle is as a whole and the greater the amount of driving range that can be extracted from the battery.

Having published white papers on its revolutionary technology mere months ago (, the production of a commercial prototype in such a short span of time has goes a long way towards validating Hillcrest’s technological claims.

“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,” commented Hillcrest CTO Ari Berger. “Implementing our technology in these systems, expected to occur by Q2 2023, will mark another important milestone by transitioning the technology out of our lab and into real world demonstrations of the Hillcrest ZVS inverter in commercial applications.”

Hillcrest’s ZVS, or soft switching capabilities will seek to overcome challenges habitually found in hard-switched wide-bandgap devices such as silicon carbide (“SiC”) traction inverters. Through the material elimination of switching losses, Hillcrest’s inverter technology has been shown to reduce the thermal management needed across the entire powertrain system. This in turn can result in substantial savings in the manufacturing process, reducing system complexity and improving system reliability by reducing stress placed upon power devices.

“In just one year, Hillcrest progressed from a 10-kilowatt proof of concept to a 250-kilowatt ZVS traction inverter commercial prototype,” said CEO Don Currie. “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.

Leveraging upon their next generation inverter solution, Hillcrest Energy Technologies will seek to deliver a step-change in the performance of electric vehicles. Not only does the inverter deliver motor efficiency gains such that it has the potential to reduce the overall size of an EV’s battery, but the reduction in battery size and consequently, the battery’s cost, can drive savings for both automotive manufacturers and end consumers.

Berger remarked, “[The] high efficient of an inverter is only the beginning of the story…from there we have several benefits at the system level.”
