Charged EVs | Hillcrest says its high-frequency inverter boosts effectivity


Inverter and management system firm Hillcrest Vitality Applied sciences has introduced the outcomes of effectivity testing on its proof-of-concept 10 kW inverter. In testing with an 80 kW motor, the corporate says testing at 20 kHz, 40 kHz and 60 kHz revealed an enchancment of effectivity at every elevated frequency degree.

“Mixed with our present check outcomes confirming inverter effectivity exceeding 99% at switching frequencies as much as 60 kHz, we’re one step nearer to demonstrating the power of our know-how to anchor the following technology of extremely environment friendly, high-performance powertrain techniques,” stated Hillcrest CTO Ari Berger.

The corporate says: “Leveraging the Hillcrest traction inverter to enhance motor effectivity in an electrical car powertrain has the potential to scale back motor measurement and cooling necessities and enhance energy density.”

Hillcrest plans to start testing a 250 kW, 800 V industrial prototype of the inverter within the coming months, and to ship a working prototype by the autumn of 2022.

“Presently, electrical motors utilized in electrical car powertrains function inside a switching frequency vary of 8 kHz to 16 kHz as a result of historic tradeoff between the very best switching conduct and acceptable thermal losses,” stated Harald Hengstenberger, Managing Director and founding father of energy electronics design firm Systematec, which collaborates with Hillcrest. “The flexibility of the Hillcrest high-efficiency inverter to function at a lot increased switching frequencies with out producing extra losses will now enable motor producers to benefit from new motor ideas not beforehand out there to them.”
