The company confirms promising advances designed to enhance EV performance

Vancouver, British Columbia, November 25, 2021 / CNW / -Hillcrest Energy Technologies (CSE: HEAT) (OTCQB: HLRTF) (FRA: 7HIA.F) (“Hillcrest” or “Company”), with clean innovation e-Mobility developers have announced additional proof-of-concept (PoC) test results on Silicon Carbide High Efficiency Inverters (SiC HEI) to eliminate switching losses and increase switching frequencies without increasing temperature. confirmed.

SiCHEI proof of concept

Hillcrest provides a proof of concept for high efficiency inverters. The company sees promising advances designed to improve EV performance. As shown in the chart, Hillcrest SiC HEI PoC dramatically reduces overall system loss as switching frequencies increase (from 10kHz to 60kHz) compared to traditional SiC inverters.Total system loss of SiC HEI compared to conventional SiC inverters (CNW Group / Hillcrest Energy Technologies Inc.)

Hillcrest’s SiCHEI PoC test results confirm its extraordinary ability to virtually eliminate significant heat generated from switching losses, thereby minimizing temperature rise. The resulting temperature rise is significantly lower than with current inverter technology. This could significantly improve the design of future electric vehicle (EV) powertrains.

These latest test results show that SiC HEI is the most efficient inverter of this type, significantly increasing the power density of future electric vehicles and other e-mobility powertrains, reducing cost, size and weight. It supports the proof of concept of electrical technology that can be done.

SiC HEI PoC is a 10kW / 800V inverter based on silicon carbide (SiC) semiconductors. The 800V has been selected to match the design currently adopted for use in the latest EV powertrain configurations.

“The company believes that HEI technology has the potential to provide a new class of energy density for previously unattainable inverters and electromechanical machines. Eliminating switching losses altogether to reduce overall system losses. Hillcrest is at the forefront of inverter technology because of its significant reductions. Hillcrest CTO Ari Berger said: Eliminating switching losses, but the entire SiCHEI inverter system. Further reduce the loss. “

Benchmark tests compare the performance of SiC HEIPoC with traditional SiC inverters. The parameters for these tests range from 470V to 870V and the frequencies range from 10kHz to 60kHz at each voltage level. In each case, SiC HEI PoC has succeeded in demonstrating its ability to eliminate switching losses and increase the switching frequency without increasing the SiC temperature under continuous operation.

As shown in the chart, SiC HEI PoC dramatically reduces overall system loss as switching frequencies increase (from 10kHz to 60kHz) compared to traditional SiC inverters.

As the efficiency achieved by HEI continues to approach its theoretical limits, very accurate measurements are required to accurately quantify the efficiency performance of HEI.

Hillcrest and its development partner, Systematec GmbH, have identified a professional third-party service with the most accurate and state-of-the-art testing equipment capable of the high accuracy required to accurately measure the efficiency of HEI. It is working.

Hillcrest continues to optimize its sophisticated control system to provide high performance levels for commercial demonstration prototypes.

Donald Curry, CEO of Hillcrest, said: “SiC HEI PoC demonstrates the value of Hillcrest’s unique combination of innovative power electronics, control methods and system design.

What Are The Main Benefits Of Comparing Car Insurance Quotes Online

LOS ANGELES, CA / ACCESSWIRE / June 24, 2020, / Compare-autoinsurance.Org has launched a new blog post that presents the main benefits of comparing multiple car insurance quotes. For more info and free online quotes, please visit https://compare-autoinsurance.Org/the-advantages-of-comparing-prices-with-car-insurance-quotes-online/ The modern society has numerous technological advantages. One important advantage is the speed at which information is sent and received. With the help of the internet, the shopping habits of many persons have drastically changed. The car insurance industry hasn't remained untouched by these changes. On the internet, drivers can compare insurance prices and find out which sellers have the best offers. View photos The advantages of comparing online car insurance quotes are the following: Online quotes can be obtained from anywhere and at any time. Unlike physical insurance agencies, websites don't have a specific schedule and they are available at any time. Drivers that have busy working schedules, can compare quotes from anywhere and at any time, even at midnight. Multiple choices. Almost all insurance providers, no matter if they are well-known brands or just local insurers, have an online presence.
