Infineon’s 650 V CoolSiC Hybrid Discrete supports bidirectional charging

Infineon‘s new 650 V CoolSiC Hybrid Discrete for Automotive contains a 50 A TRENCHSTOP 5 fast-switching IGBT and a CoolSiC Schottky diode. The combination supports bidirectional charging, making it suitable for fast-switching automotive applications such as onboard chargers, power factor correction, and DC-DC or DC-AC converters. Infineon says the integrated fast-switching 50 A IGBT enables… Read more »

Marelli launches SiC power module for motorsport EVs

Global automotive supplier Marelli has launched a power module for motorsport EV applications. The module, which was completely developed in the company’s Corbetta (Italy) facility, is based on silicon carbide (SiC) technology and uses a new direct cooling solution.  The new module, called EDI (Enhanced Direct-cooling Inverter), was developed by Marelli Motorsport with the Fraunhofer… Read more »

Nexperia extends MOSFET line-up with AEC-Q101-qualified half-bridge package

Nexperia has announced a series of half-bridge (high-side and low-side) automotive MOSFETs constructed in the space-saving LFPAK56D package format. The half-bridge configuration of two MOSFETS is a standard building block for many automotive applications, including motor drives and DC/DC converters. The new package provides a half-bridge solution in one device, and occupies a 30% smaller… Read more »

Silicon Mobility releases new EV powertrain control software

Silicon Mobility has announced the release of OLEA APP INVERTER, a software application platform for control of inverters and electric motors.  The application is based on the OLEA T222 FPCUs parallel architecture, which allows real-time control of power electronics and motors. It provides torque and speed control using Field Oriented Control (FoC) and variable Space… Read more »

High-voltage EV battery packs: benefits and challenges. More voltage, more better?

In 2020, Porsche delivered just over 20,000 units of its luxury Taycan EV—the first vehicle from a major automaker to sport an 800 V (nominal) battery, which is more than double the voltage of its competitors (and firmly into light-rail and switchyard locomotive territory, actually). It appears that many other EVs will soon follow in… Read more »

Cree launches new silicon carbide power module portfolio

Cree has announced the launch of its Wolfspeed WolfPACK power modules for a diverse range of industrial power markets, including EV fast charging, renewable energy, energy storage and industrial power applications. The new modules use 1,200 V MOSFET technology, and are designed to deliver maximum efficiency in small packages. “The introduction of the Wolfspeed WolfPACK… Read more »

AEM’s new control board increases Tesla Drive Unit’s power in EV conversions

AEM EV plans to release a comprehensive control system for EV conversions using a Tesla Large Drive Unit (LDU) Base Drive that increases horsepower over the factory output. AEM’s Inverter Control Board was co-developed with Cascadia Motion, a maker of EV propulsion systems, and is intended to be combined with AEM EV’s VCU200 vehicle control… Read more »

Nexperia releases 80 V resistor-equipped transistor for 48 V automotive circuits

Nexperia has introduced its 80 V RET (resistor-equipped transistor) family. The company says the new RETs, or “digital transistors,” provide enough headroom for use in 48 V automotive circuits. RETs save space and reduce manufacturing costs by combining the bias resistor and bias-emitter resistor in the same SOT23 (250 mW Ptot) or SOT323 (235 mW… Read more »

Rhombus launches new bidirectional charging solution for medium- and heavy-duty EV fleets

Rhombus Energy Solutions has launched a new bidirectional “EV charging dispenser.” The RES-D2-CS20 has been certified by Underwriters Laboratory (UL) and the CSA Group for use in medium- and heavy-duty fleet applications. The company calls it a perfect match for the Rhombus 60 kW and 125 kW Power Conditioning Systems. Rhombus’s bidirectional charger enables Vehicle-to-Grid… Read more »
