- A new white paper demonstrates the value of Hillcrest soft-switching technology for increased power density through reduced capacitor and overall inverter size.
- The Hillcrest EV commercial prototype inverter is designed with 5 to 10 times the capacitance of current systems.
- Potential to disrupt power inverter design across the automotive industry
VANCOUVER, British Columbia, August 17, 2022 (GLOBE NEWSWIRE) — Hillcrest Energy Technologies (CSE: HEAT) (OTCQB: HLRTF) (FRA: 7HIA) (the “Company”) develops innovative power conversion technology and control system solutions for next-generation electric vehicles and electrical systems. A clean technology company. We are pleased to announce the release of a new technical white paper outlining the benefits of Hillcrest inverter technology and how its soft-switching capability relates to capacitors in power conversion systems.
A previous Hillcrest white paper shared test results demonstrating the value of operating electrical systems at higher switching frequencies to eliminate losses. A recent white paper shows how operating at higher switching frequencies not only significantly reduces the size of capacitors in systems, but also improves power quality, system reliability, and component life. It explains what
In inverters, capacitors allow pulses of current to occur at different times and at different frequencies. This is an energy buffer function. It also smoothes the pulse and reduces the amount of peak-to-peak ripple voltage in the process. There is typically a bank of capacitors within the inverter, often making up a large portion of the overall component size.
Using Hillcrest’s soft-switching inverter technology to enable switching at higher frequencies reduces the size of the required capacitors, reducing the overall size, weight, and cost of the inverter, thus increasing power density. significantly improved. The ability to operate at higher switching frequencies using Hillcrest’s soft-switching technology offers other substantial benefits such as improved power quality, elimination of switching loss materials, and reduced electromagnetic compatibility issues. To do.

“Typical EV traction inverters today have capacitances between 600 microfarads and 1 millifarad, whereas the Hillcrest traction inverter commercial prototype design assumes 1/5th to 1/10th the capacitance. We do,” said Hillcrest CTO Ari Berger. “Dramatically reducing capacitor and inverter size and increasing power density, combined with improving power quality and system reliability, could disrupt power inverter design across the automotive industry.”
