Manufacture of first ZVS-enabled power module underwayZVS-enabled power modules to be integrated into Hillcrest SiC traction inverterDynamic load demonstration testing underway with Global Tier One Automotive Supplier’s motor subsystemVANCOUVER, BC, June 22, 2023 /CNW/ – Hillcrest Energy Technologies HEAT HLRTF 7HIA (“Hillcrest” or the “Company”), an innovative clean technology company revolutionizing power conversion technologies and advanced control system solutions, is pleased to provide shareholders an update on recent activities.

Manufacture of Hillcrest ZVS-enabled Power ModulesWith the design phase now complete, the Company is now manufacturing the EV industry’s first silicon carbide (SiC) power module prototype optimized for Hillcrest’s proprietary Zero Voltage Switching (ZVS) technology. Manufacturing is taking place at the facilities of the Company’s strategic partner, Systematec GmbH, in Germany.The integration of the Company’s ZVS-enabled power module into the Hillcrest SiC traction inverter will create the world’s first ZVS-optimized SiC traction inverter.Hillcrest Chief Technology Officer, Ari Berger, commented, “We’ve already demonstrated industry-leading results with our current ZVS-enabled SiC traction inverter.  Integrating these new power modules into our inverter allows us to maximize the benefits of our ZVS technology. We are now able to deploy further improvements in switching control and operation at higher switching frequencies to achieve even more impressive levels of power density, system efficiency and further reductions in electromagnetic interference (EMI) behaviour for applications up to 1,000 volts.”Hillcrest Chief Commercialization Officer, James Bolen, added, “The EV industry is shifting toward the use of power modules and away from the use of discrete power solutions because they are complicated, have significant power limitations and take up valuable space. The Hillcrest ZVS-enabled power module addresses this trend and offers all the advantages of our ZVS technology coupled with the significant improvements in size, reliability, design capabilities and reduced time to market.”Power modules are a critical component in all high energy-density power conversion equipment, such as automotive traction inverters. They consist of a substrate containing power semiconductor devices (silicon carbide dies), connected to form a circuit that provides excellent electrical and thermal contact and insulation. Hillcrest’s ZVS power module prototypes are being developed in collaboration with the Company’s strategic partner, Systematec GmbH, with Hillcrest retaining all intellectual property.The Hillcrest SiC traction inverter harnesses the power of the Company’s proprietary ZVS technology platform. Extensive lab tests and simulations have showcased substantial improvements in system-level efficiency, performance, and reliability for electric systems such as electric vehicles and stationary energy generation and energy storage systems.Demonstration Testing with Global Tier One Automotive SupplierDynamic load demonstration testing with a specialized motor provided by a Global Tier One Automotive Supplier is underway at Hillcrest’s R&D lab in Vancouver. Completion of the tests and the Global Supplier’s acceptance of the results are expected next month and will conclude milestone two of the Company’s previously announced joint development project. Work then starts on the next milestone which includes a series of on-site demonstrations at the customer’s facilities. Upon successful completion of all milestones, Hillcrest and the Global Tier One Automotive Supplier anticipate entering into a definitive commercial agreement.CEO Don Currie Participates in Interview to Discuss Achievements and 2023 OutlookHillcrest CEO, Don Currie sat down to discuss recent Company achievements and the opportunities on the horizon for 2023. Topics included the Company’s core technologies centered around the proprietary implementation of Zero Voltage Switching (ZVS), milestones and the path to commercialization, and additional applications for the Hillcrest ZVS technology beyond electric vehicles.
