파워 질화갈륨(GaN) 시장(2027-2037년)

The global power gallium nitride (GaN) market has moved decisively from technological promise to production reality, establishing itself as one of the most disruptive forces in power electronics. What began as a niche alternative to silicon has matured into a strategically vital semiconductor category, and the market is now on a steep growth trajectory as adoption accelerates across an expanding set of end markets. This report captures the industry's transition from an early-adopter phase dominated by consumer devices into a diversified, application-rich market underpinned by data centers, automotive electrification and robotics.

GaN's core value proposition is enduring: superior switching frequency, higher efficiency, greater power density and better thermal behaviour than silicon, at a cost structure increasingly competitive with both silicon and silicon carbide. Consumer and mobile applications - above all fast chargers - drove the first wave of volume and ecosystem maturity, and remain a substantial share of demand. The next inflection is being catalysed by AI data centers: the industry-wide shift toward high-voltage DC power architectures, anchored by NVIDIA's reference designs, has triggered a wave of qualification activity among leading suppliers including Texas Instruments, Navitas, Infineon, Innoscience, onsemi and Power Integrations. Automotive represents a major growth vertical, with onboard chargers, DC-DC converters and LiDAR pushing adoption, while humanoid robotics has emerged as a credible new demand driver.

The competitive landscape is being reshaped by consolidation and vertical integration. Landmark acquisitions - Infineon-GaN Systems, Renesas-Transphorm, STMicroelectronics-Exagan - have concentrated capability among incumbent IDMs, even as Innoscience retains market leadership from its position as the world's largest 8-inch GaN-focused manufacturer. TSMC's exit from GaN foundry services redistributed customers and elevated GlobalFoundries, while the transition to larger wafer diameters and engineered-substrate innovation are redrawing the cost curve. Meanwhile, China's rapid domestic build-out, geopolitical trade friction and gallium supply concentration introduce genuine structural risk.
