Power Semiconductors (Si, SiC, GaN) — Switching Devices Market Analysis

Cold Cathode Fluorescent Lamp CCFL Transformers Market to Reach USD 302.6 Million by 2033 at 3.1% CAGR

Silicon MOSFETs and IGBTs remain dominant in CCFL inverter output stages, though research prototypes using GaN switches have demonstrated superior efficiency at 50kHz–150kHz operating frequencies (openalex:W4384820020). Mainstream CCFL transformer designs remain on Si due to cost and the absence of a performance gap that would justify GaN premiums in a legacy repair market.
