During 95% of the driving time, the EV’s traction inverter is operating under 30% of its full rated load. At low loads, the switching loss of the inverter will be much more dominant than the conduction loss. The typical mission profile of the traction inverter isTable 1.
When comparing semiconductor solutions for traction inverters, standard solutions using state-of-the-art silicon IGBTs may result in a low-cost traction inverter. However, this may not necessarily achieve the size, weight, and efficiency the vehicles require when battery/range costs are included.

STMicroelectronics is betting big on silicon carbide (SiC) as a critical part of its strategy and revenues, as it outlined at its ania, Italy, plant last week. In all the company’s recent quarterly and annual results briefings, CEO Jean-Marc Chery has consistently stated his intent to capture 30% of the SiC market, projected to be a $3.7 billion market by 2025.
In addition, using cascodes in place of diodes in the booster means the booster-plus-inverter can process power in two directions. The cascodes can act as a switch or as a diode depending on the direction of power flow, so the system can perform as a DC-to-AC inverter or an AC-to-DC active front end rectifier, which may be needed if the solar generator is to store energy or power a UPS.

Silicon (Si)-based IGBTs have been on the market for more than 30 years. The technology has quickly evolved, reducing the costs and improving performance at the same time. As Si devices approach their physical limits, wide-band-gap devices, in particular made from silicon carbide (SiC), have emerged on the market, offering better performance thanks to their intrinsic properties.
Coined with the low switching losses of silicon carbide MOSFETs, this enables losses in inverter operation to be reduced by around 60 per cent compared to silicon IGBTs. In addition to optimised performance, reliability in terms of achieving high short-circuit, cosmic ray and gate-oxide robustness is important for designing efficient high-voltage appliions in electric cars.
