Hillcrest Energy Technologies (CSE: HEAT) (OTCQB: HLRTF) (FRA: 7HIA.F), a clean technology company developing transformative power conversion technologies and control system solutions for next-generation EVs and electrical systems, has completed proof of concept testing that demonstrates the elimination of switching losses with its traction inverter.

A comparison of losses between soft-switching and hard-switching was calculated by Hillcrest. The system was tested with 470V DC-link voltage under 5A load with 20kHz switching frequency. The Hillcrest inverter achieved an average of more than 90% fewer switching losses and a roughly 90% reduction in dV/dt compared to the conventional, hard-switched inverters found in many EVs today.
