Renesas introduces second-generation gate driver integrated circuit for EV inverters

Semiconductor supplier Renesas Electronics has announced a new gate driver integrated circuit (IC) designed to drive high-voltage power devices, such as insulated gate bipolar transistors (IGBTs) and silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors (MOSFETs) for EV inverters.  Gate driver ICs are designed to provide an interface between the inverter control microcontroller unit (MCU) and the… Read more »

Renesas launches new generation of automotive Intelligent Power Devices

Japanese semiconductor manufacturer Renesas Electronics has revealed a new automotive Intelligent Power Device (IPD) that’s designed to safely and flexibly control power distribution within vehicles. The new RAJ2810024H12HPD is available in a small TO-252-7 package and reduces the mounting area by about 40% compared to the conventional TO-263 package product. Renesas also says that the… Read more »

STMicroelectronics introduces improved silicon-carbide power modules

Global semiconductor manufacturer STMicroelectronics has released new high-power modules for EVs that it says will boost performance and driving range. They will be used for Hyundai’s E-GMP EV platform, which is shared by the Kia EV6 and other models. The company’s five new third-generation SiC-MOSFET-based modules cover a range of power ratings and operating voltages… Read more »

Delta Electronics demonstrates 400 kW solid-state transformer-based EV charger

Delta Electronics (Americas) demonstrated a next-generation SiC MOSFET solid-state transformer-based 400 kW EV charger at a recent event attended by representatives of project partners GM, DTE Energy and NextEnergy. Delta’s “extreme fast” EV charger uses a three-phase 13.8 kV medium-voltage SiC MOSFET SST topology. It provides 500 A of charging current, and the company claims… Read more »

Power electronics thermal limits and how to not exceed them

To someone who isn’t involved in power electronics design, it might seem unreal that the amount of power a component can handle depends more on how effectively waste heat can be removed from it than it does on the specific electrical ratings. Sure, the voltage and current ratings are important (especially the voltage rating), but… Read more »

A closer look at brushed AC motors in EVs

Everything old is new again: BMW’s fifth-generation eDrive features a wound-field synchronous AC motor Brushed DC (and AC/DC universal) motors are much maligned for a number of reasons, but one of the chief—if, perhaps, somewhat exaggerated—complaints is that the graphite brushes, and the segmented copper commutator they ride on, wear out over time, all the while producing… Read more »

NIO selects onsemi’s VE-Trac Direct SiC power modules for its next-gen EVs

Power and sensor technology company onsemi (formerly ON Semiconductor) has announced that NIO selected its VE-Trac Direct SiC power modules for its next-generation EVs. The SiC VE-Trac Direct is a 900 V power module with integrated single-side direct cooling that incorporates onsemi’s second-generation SiC MOSFET technology. onsemi says “An integrated pin fin baseplate enables direct… Read more »
