Inverter and management system firm Hillcrest Power 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 current 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 expertise to anchor the following era 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 automobile powertrain has the potential to cut 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 automobile powertrains function inside a switching frequency vary of 8 kHz to 16 kHz because of the 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 larger switching frequencies with out producing extra losses will now permit motor producers to make the most of new motor ideas not beforehand obtainable to them.”
