Power Semiconductors Aren't Silent, They're Charging Up

$41.3 billion, a 7.1% CAGR through 2031. These figures from Yole Group have turned the power semiconductor industry from "quietly making bank" into an "open card." Infineon, onsemi, STMicroelectronics—these names are no longer just chatter among engineers but focal points for capital markets. But if you think this is just another rerun of the "chip shortage" story, you're wrong. Power semiconductors are currently undergoing an identity shift from "supporting role" to "lead role," driven by the underlying demand restructuring across trillion-dollar tracks like new energy, automotive, photovoltaics, and energy storage.
