SiC Demand at an Inflection Point — How EV Slowdown Has Opened Industrial Market Opportunities

Slower EV demand growth has prompted a downward revision of SiC market forecasts. Meanwhile, demand from industrial equipment, solar, and data centers is expanding faster than expected, and demand diversification is taking hold as a structural shift. We examine the implications for evaluating supplier demand portfolios.

EV Power Semiconductor Application Selection Matrix

The cost of SiC power modules per inverter is 2 to 3 times higher than traditional Si-based modules, yet EV manufacturers are accelerating their transition to SiC because the increased efficiency and reduced size of the overall system offset this higher component cost; however, it is not simply a matter of "using SiC," as EV power conversion systems are divided into multiple applications, each with its own...

SiC Inverter for EVs: Loss Calculation and Efficiency Improvement

A 1% increase in conversion efficiency for EV inverters translates to a difference of several kilometers in driving range; when design engineers face the challenge of improving real-world efficiency beyond catalog values, the first question they encounter is "which losses to calculate and how." Without correctly decomposing the loss breakdown, SiC may not yield the expected efficiency improvements.
