Gallium Nitride Power Chips for EVs Market Size
The global gallium nitride (GaN) power chips for EVs market size was valued at USD 297 million in 2024. The market is set to expand from USD 360.1 million in 2025 to USD 1.5 billion by 2034, at a CAGR of 15.5% according to latest report published by Global Market Insights Inc.
As the automakers adopted high frequency, high density conversion stages at volume. The inflection tracks surging EV sales and charging buildouts that expand the total pool of power electronics content per vehicle and per charging site. Global EV sales reached 17 million in 2024 and exceeded 20% of new car sales, while the global fleet neared 58 million, driving sustained demand for efficient power conversion across vehicles and infrastructure.
From 2025 to 2034, the market is forecast to grow from USD 360.1 million to USD 1.52 billion at a 15.5% CAGR, supported by fleet expansion, rising OBC power levels (moving toward 11–19.2 kW), and increased GaN penetration across DC–DC converters and charger topologies where high-frequency operation yields system-level gains. Year-over-year growth moderates from the early triple-digit surge to low 20s in the mid-2020s and down toward the mid-teens into the early 2030s as volumes scale and pricing normalizes.
GaN’s On Board Charges edge is clear in hardware demonstrations, 6.6 kW GaN design at 100 kHz achieved 99% peak efficiency while cutting volume by 53% and mass by 79% versus a silicon baseline, lifting power density from 3.9 kW/L to 10.5 kW/L and specific power from 1.6 to 9.6 kW/kg key levers for EV range and packaging. Recent OBC prototypes based on 650 V GaN switches have also demonstrated high-density, bidirectional operation suitable for V2G-ready designs.
Public charging points doubled between 2022 and 2024 to over 5 million globally, fast chargers rose to 2 million, and ultra-fast units (>150 kW) increased by more than 50% all of which intensify the need for compact, efficient conversion where GaN thrives in PFC and DC–DC stages. Because of this, we expect charger makers to standardize higher-frequency designs in space-constrained urban sites and depot charging, reinforcing GaN demand in the mid-voltage class.
North America’s GaN adoption is supported by federal incentives for EV purchases and charging buildouts, including clean vehicle credits and the NEVI program funding fast charging corridors. The U.S. market benefits from government roadmaps targeting 200 kW, 800 V traction systems and high-density OBC benchmarks, which steer suppliers toward high-frequency GaN designs in the near term. The U.S. electric vehicle market reached roughly 1.6 million sales in 2024 (about 10% share), a base that underpins rising OBC/DC–DC volumes that favor GaN. Canada’s policy support and provincial programs add further momentum as local charging networks expand.
Asia Pacific market leads globally, with China accounting for nearly two-thirds of EV sales and dominating public charging installations at over 3.25 million units, creating the world’s largest OBC and charger opportunity for GaN. China’s policies, trade-in schemes, and V2G roadmaps reinforce growth, while India’s PM e-DRIVE and Southeast Asian incentives broaden the regional base. Japan and South Korea contribute advanced R&D and supply chain capabilities, and as 800 V platforms rise in premium segments, readiness for high-voltage GaN will shape the next phase of market development in Asia Pacific.

Gallium Nitride Power Chips for EVs Market Trends
The industry is shifting from stand-alone discretes to integrated half-bridge stages and modules that co-package GaN switches with drivers and protection, cutting layout sensitivity and EMI while improving thermal paths. Public–private programs have accelerated commercialization of WBG technologies, catalyzing integrated GaN solutions for chargers and OBCs. In parallel, automakers are integrating multi-functional power domains, reinforcing the trend toward higher integration levels.
Public charging points doubled between 2022 and 2024 to over 5 million, and ultra-fast chargers (>150 kW) jumped by 50% in the same period. Regulatory mandates for high-power charging stations are lifting the bar for dense, efficient conversion stages. Extreme fast-changing requirements push power electronics toward higher frequency and density an alignment where GaN performs exceptionally well in PFC and LLC stages.
Demonstrated OBC converters show GaN raising power density by 170% while trimming mass 79% versus silicon baselines, at 99.0% peak efficiency in a 6.6 kW dual active bridge prototype. Analyses highlight that GaN devices can operate at much higher switching frequencies with significantly lower conduction losses versus silicon, enabling shrinkage of magnetics and cooling hardware while cutting losses by 60–80% in advanced converters. Design teams are also re-optimizing switching frequencies to balance converter gains with motor parasitic losses in traction-adjacent use-cases.
Research programs have shown 1.2 kV GaN MOSFETs with high-κ HfO2 gate dielectrics achieving record low gate leakage and improved current density, positioning vertical GaN to compete with SiC at ≤1.2 kV once substrates and process maturity converge. Yet, automotive qualification for 800 V+ and 150 kW traction remains ahead; industry roadmaps expect readiness near the decade’s end given native GaN substrate costs and reliability proofs still in progress.
