MOSFETs are fast-acting digital switches, used to transform electricity, across new energies and digital devices. MOSFET power losses are built up from first principles in this data-file, averaging 2% per…
…application in practically all new energies (note here). However, measuring the price of SiC MOSFETs in terms of the cost per kg of SiC is a bit like measuring the…
…charted the company’s revenues, employee count, market share in MOSFETs, market share in SiC devices, market share in SiC materials, total estimated revenues from SiC and proportionate exposure to SiC….
…the MPPT in solar, to wind turbines, to charging and discharging batteries, such as in electric vehicles. DC-DC converters invariably contain one or more MOSFETs, diodes, inductors and capacitors. Think…
…(SiC) is a fundamentally better semiconductor for power-electronic applications, yielding 1-10% efficiency improvements (page 5). Why is SiC “better”? The answer stems from material properties, including 100x lower on-resistance, 10x…
…up to 13% higher range than today’s inverters, especially for use in EV powertrains; but also in wind, solar, batteries and fast-chargers. It is based on SiC semiconductors. This Hillcrest…
…interesting incremental jolts for the energy transition is the 1-10pp higher efficiency and rising market share of SiC MOSFETs. Leading companies in SiC and MOSFETs are screened here. (10) Inertia…
…earths for wind turbines; and lithium and SiC MOSFETs for electric vehicles. Ultimately these value chains also need to decarbonize in some non-inflationary way, which is a focus in our…
This 14-page note explains the crucial power-electronics in an electric vehicle fast-charging station, running at 150-350kW, to charge up an entire EV in 10-30 minutes. Most important are power-MOSFETs, comprising…
…which promise 2-3x higher power densities, even versus Tesla’s world-leading PMSRMs while surpassing 96% efficiencies (note here). And SiC power electronics that unlock faster and more efficient switching in the…
