Rhopoint Components is to supply a 1.2kV 260A three-phase silicon carbide power module for electric vehicles. Made by Cissoid and called CMT-PLA3SB12340, it can supply its 26A at 90°C, and up to 340A at 25°C. This is a complete power module, including output-to-baseplate (5kVdc for 1min) and input-to-output (3kV for 1min) isolation, power supplies to feed the secondary side gate ...

Undocumented communication devices, including cellular radios, have been found in solar power inverters and energy storage batteries, according to Reuters. There is little additional information at this time: the news organisation has not been able to discover the identity of the manufacturers affected, and is not naming its human sources. While these undocumented links could simply be alternative routes for ...

US car maker Rivian has signed up Infineon to supply traction inverter power modules, microcontrollers and power ICs for its ‘R2’ vehicle platform, expecting to start in 2026. The power modules will be in Infineon’s HybridPack Drive G2 format (pictured) and include both silicon and silicon carbide components. Along with these, Rivian has picked infineon’s established TC3x MCUs, not not ...

Power component maker Cissoid has teamed up with automotive engineering services provider Edag Group to develop SiC traction inverters for electric mobility. “This collaboration brings together Cissoid’s expertise in silicon carbide power semiconductor modules and controls with EDAG’s know-how in the design, integration and validation of electric powertrains,” according to Cissoid. “The two companies aim to offer e-mobility OEMs and ...

Cambridge GaN Devices has patented a technique for lowering losses in 100kW+ IGBT-based vehicle traction drives, at lower cost than all-silicon-carbide inverters, it said. It involves connecting GaN hemts in parallel with large silicon IGBTs, and has been branded ‘Combo ICeGaN ‘. “Today, inverters for EV powertrains either use IGBTs which are low cost but inefficient at light load conditions, ...

EPC has introduced an evaluation board implementing a 40Arms (60A peak) three-phase inverter that will run from 30V to 130V. Called EPC91200, it is “suitable for 80  and 110V battery systems commonly used in industrial automation, agricultural machinery and material handling equipment like forklifts,” according to the company. The inverter is designed around EPC’s 150V 3mΩ EPC2305 GaN HEMT, a ...

Renesas is to reveal the ‘8-in-1’ electric vehicle power axle prototype that it has developed with Nidec. X-in-1 axles are an attempt to put more and more of an electronic vehicle’s power systems in a single integrated unit. Last year, the two companies showed their 6-in-1 axle proof-of-concept, combining; motor, inverter, gearbox, dc-dc converter, on-board charger and power distribution unit. ...

Electrocube has created a series of metallised polypropylene film capacitors for high power inverters in military and commercial, land and sea, applications. Voltage ratings of 400, 600 and 1,000V are available, and capacitances from 100nF to 10μF, plus 15 and 20μ in the 400V range “Able to handle high surge currents without degrading, Electrocube’s 985B is a rugged, non-inductively wound ...

Hyundai uses 800V batteries in some of its electric vehicles, but not all road-side chargers have an 800V option, so some sort of 400V to 800V inverter is required in the vehicle. And for fast charging, that has to handle a heck of a lot of current – maybe 200A. Rather than have a separate box, and noting that vehicle ...

Transistor maker GaN Systems has signed a memorandum of understanding with QPT, a start-up with patents covering power modules  designed using RF techniques to get the best out GaN transistors. The MOU covers the use of QPT technology and GaN Systems transistors in electric vehicle power converters – in particular: 100kHz to 20MHz hard-switching high-power and high-voltage converters. “We are ...
