GaN-on-Si Traction Inverter: What AVL and VisIC Show
AVL and VisIC report 99.67% efficiency at 10 kHz in GaN-on-silicon traction inverter dyno testing at 400V; what it means for SiC and GaN wafer sourcing.
Technical analysis on silicon, SiC, and GaN wafers, GaAs and InP substrates, EV power electronics, and Canada’s semiconductor materials supply chain.

A conditional $1.5B Pentagon commitment to Wolfspeed funds SiC capacity but does not allocate wafers to outside buyers; what procurement teams should track and how to dual-source.
Moving SiC from 150mm to 200mm gives 1.78x gross wafer area and one report claims ~35% lower cost per chip — what changes on yield and who supplies 200mm.
China controls 98.9% of primary gallium and prices sit at 9–10x 2023 levels — what that means for GaN epiwafer and GaAs substrate supply through 2030.
UBS says wafer makers need 40–50% higher prices to add capacity and sees 20%+ annual increases in 2027–2028; what North American buyers should do now.
China’s indium export controls and AI optical-interconnect demand pushed six-inch InP wafers up ~250% to about $5,000 — what IQE’s 7 September results signal and how buyers can second-source.
Wavelength, mobility, cost, and applications compared — from RF power amplifiers to 1550 nm fiber optics and AI data-center co-packaged optics.
FABrIC, CMC Microsystems, ventureLAB, and Canada’s Semiconductor Council are building a domestic chip ecosystem. Here is why local materials distribution is the supply-chain layer Canada still needs.
