Hillcrest says its ZVS inverter cuts motor voltage overshoot by more than 90%

Power conversion developer Hillcrest Energy Technologies has announced peer-reviewed test results comparing its zero-voltage-switching (ZVS) inverter technology with a conventional hard-switched silicon carbide (SiC) inverter. Hillcrest says that in side-by-side testing, ZVS reduced motor-terminal voltage overshoot by more than 90%, from 50% above the DC-link voltage to 4% above it. Read more

Ferrstron road-tests a 150 kW ferrite-magnet motor that uses no rare earths

Indian electric powertrain developer Ferrstron Powertrains has road-tested a prototype 150 kW, 400 Nm powertrain in a 2.3-ton multi-utility vehicle. The powertrain’s motor uses ferrite magnets instead of rare earth magnets. Ferrstron is developing electric powertrains for heavy-duty trucks and buses, high-speed trains and marine vessels, plus generators for direct-drive Read more
