SiC half-bridge handles 1.8MW in under 500ns

Infineon XHP2 package with AlSiC baseplate

Aiming at vehicle traction, Infineon has put a pair of 3,300V 1,000A 1.9 mΩ silicon carbide trench mosfets into its 100 x 140 x 40mm ‘XHP 2’ module housing, calling the module FF2000UXTR33T2M1. This package is rated for 6kV testing, and achieves 2.6kV partial discharge extinction. Creepage is 40mm terminal to baseplate and 34mm between terminals. Clearance is 31 and ...

Cissoid intelligent SiC power modules for industrial EV

Cissoid SiC inverter AEV vehicle

Applied EV has picked Cissoid to supply silicon carbide based inverter modules for its autonomous electric vehicles. The module, CXT-ICM3SA, was introduced at APEC earlier this year and combines a three-phase 1.2kV SiC mosfet bridge – rated at 340 to 550A depending on model – a driver board and a control board in a stack. The control board is built ...

Little Car Company hits three years

Little Car Company mini electric blower Bently

Specialist electric car maker The Little Car Company is celebrating three years since it delivered its first vehicle. The company creates slightly scaled down versions of classic vehicles, powered by electric motors rated at up to 28kW. So far is has delivered 400 vehicles to over 50 countries, spread between its Bugatti Baby II, Aston Martin DB5 Junior and Ferrari ...

Triple current sensor for 800V traction inverters up to 1MW

LEM HAH3DR 800V three phase traction current sensor

LEM has announced three-phase current sensors that fit silicon carbide power modules typically used in 800V vehicle traction inverters. “Developers of automotive traction inverters are increasingly using three-phase power modules such as Hybridpack Drive from Infineon, Acepak Drive from ST Microelectronics, SSDC from ON Semi, and others such as Starpower and CRRC,” according to LEM. “The current sensor offers current ...

Automotive traction inverter hits efficiency 98.5% at 5% load (and peaks at 99.57%)

Pre-Switch efficiency curve 2023

San Jose based Pre-Switch is reporting 98.5% efficiency at 5% load from its 800Vin ‘CleanWave2’ prototype inverter. Peak efficiency is 99.57%. It is a 100kHz forced-resonant, soft-switching inverter, controlled by an AI algorithm (more on the technology here). “Over a year ago we announced peak efficiency of over 99%. Since that time, we have been improving our AI algorithm to ...

1.5kA current sensor for EV traction inverters is only 29mm tall

LEM EV traction current sensor HSTDR

Aiming at electric vehicle traction inverters, LEM has managed to shrink a 1.5kA current sensor into 29 x 21 x 12mm and 27g. “HSTDR current sensor is significantly more compact than a traditional C-core sensor, making it much easier to be integrated into space-limited inverter boxes,” said LEM. The technology is open-loop Hall effect and the core, integrated bus bar ...

Onsemi and VW to develop SiC traction inverter

In the latest deal by a car maker in the scramble for silicon carbide, Volkswagen has signed a strategic agreement with onsemi to provide modules and semiconductors for the traction inverters for VW’s next-generation electric vehicle platform. Teams from the two companies, revealed onsemi, have been collaborating for more than a year to optimise power modules, and pre-production samples are ...

Electronica: MCUs for two-motor electric vehicle traction inverters

NXP S32K39 MCU vehicle electrification

NXP is aiming at electric vehicles traction inverters for up to two motors with its S32K39 microcontrollers. “The MCUs support IGBT as well as SiC and GaN,” according to the company. “It has enough compute power to support six-phase or two three-phase motors controlled by dual 200 kHz control loops, while hosting AI, machine learning or other monitoring applications. It ...
