氮化鎵(GaN)電動車充電器市場機會、成長促進因素、產業趨勢分析及預測(2025-2034年)Gallium Nitride (GaN) EV Charger Market Opportunity, Growth Drivers, Industry Trend Analysis, and Forecast 2025 - 2034 |
||||||
2024 年全球氮化鎵 (GaN) 電動車充電器市值為 11.4 億美元,預計到 2034 年將以 24.3% 的複合年成長率成長至 97.7 億美元。

市場正從獨立的離散裝置向整合式半橋級和模組轉型,這些整合式半橋級和模組將氮化鎵(GaN)開關與驅動器和保護功能相結合。這種整合降低了佈局敏感性和電磁干擾(EMI),同時提高了散熱性能。公私合作計畫加速了寬禁帶(WBG)技術的商業化,推動了車載充電器(OBC)和電動車電源系統採用整合式GaN解決方案。汽車製造商正日益整合多功能電源域,從而支援更高水準的裝置整合。 OBC轉換器的展示表明,與矽基系統相比,GaN可以將功率密度提高170%,重量減輕79%,並在6.6 kW雙有源橋原型中實現了99%的峰值效率。 GaN元件可以以比矽更高的頻率和更低的導通損耗進行開關,從而可以縮小磁性元件和冷卻系統的尺寸,同時在先進的電動車轉換器中將損耗降低60-80%。設計團隊也正在最佳化開關頻率,以平衡轉換器性能和馬達寄生損耗。研究表明,採用高HfO2閘極介質的1.2 kV GaN MOSFET可實現極低的閘極漏電流和更高的電流密度。一旦襯底和製程技術成熟,垂直GaN元件有望在1.2 kV應用領域與SiC元件展開競爭。然而,由於成本和可靠性方面的考慮,800 V以上和150 kW牽引應用的汽車級認證仍在開發中,預計要到本世紀末才能實現。

橫向氮化鎵元件市場佔有率達到70%,預計從2025年到2034年將以16.1%的複合年成長率成長。橫向氮化鎵裝置在電動車電力電子領域佔據主導地位,應用於車用電池、直流-直流轉換器和高達650V的輔助系統。與矽相比,其在矽基板上的AlGaN/GaN HEMT結構具有高電子遷移率和臨界場強,在高阻斷電壓下可實現低導通電阻。
中壓(100-650V)市場在2024年佔據了67%的市場佔有率,預計到2034年將以16%的複合年成長率成長。中壓GaN元件已廣泛應用,因為大多數車載電池(目前為400V,未來將上升至800V)和許多DC-DC轉換器都屬於此電壓範圍。 GaN的高頻性能可直接提升6.6-19.2kW車載電池系統中功率因數校正和LLC或諧振轉換器級的效率和功率密度。
預計到2024年,中國氮化鎵(GaN)電動車充電器市場規模將達到7,340萬美元。中國電動車銷量佔全球近三分之二,其龐大的市場規模使其成為GaN裝置最大的潛在市場,因為每輛電動車都需要車載充電器、DC-DC轉換器和相容的充電基礎設施。這一產能規模使中國遙遙領先日本、韓國和印度等其他區域市場。
全球氮化鎵 (GaN) 電動車充電器市場的主要參與者包括 Transphorm、Navitas、德州儀器 (Texas Instruments)、GaN Systems、EPC、意法半導體 (STMicroelectronics)、羅姆半導體 (ROHM Semiconductor)、英飛凌科技 (Infineon Technologies Technologies)、Ingrscience 和 Infinations。各公司正透過加大研發投入來提升 GaN 裝置的效能、效率和可靠性,進而鞏固自身市場地位。與汽車製造商和充電器製造商的策略合作加速了 GaN 技術的普及應用。拓展產品組合,推出中高壓解決方案,取得汽車產業認證,以及開發整合模組,均有助於提高市場滲透率。此外,各公司也致力於透過襯底創新、擴大產能和最佳化供應鏈來降低成本。

The Global Gallium Nitride (GaN) EV Charger Market was valued at USD 1.14 billion in 2024 and is estimated to grow at a CAGR of 24.3% to reach USD 9.77 billion by 2034.

The market is transitioning from standalone discrete devices to integrated half-bridge stages and modules that combine GaN switches with drivers and protection features. This integration reduces layout sensitivity and EMI while improving thermal performance. Public-private initiatives have accelerated the commercialization of wide-bandgap (WBG) technologies, driving the adoption of integrated GaN solutions for onboard chargers (OBCs) and electric vehicle power systems. Automakers are increasingly integrating multifunctional power domains, which support higher levels of device integration. Demonstrations of OBC converters indicate that GaN can increase power density by 170% and reduce weight by 79% compared to silicon-based systems, achieving peak efficiencies of 99% in a 6.6 kW dual active bridge prototype. GaN devices can switch at higher frequencies with lower conduction losses than silicon, allowing smaller magnetics and cooling systems while reducing losses by 60-80% in advanced EV converters. Design teams are also optimizing switching frequencies to balance converter performance with motor parasitic losses. Research has shown that 1.2 kV GaN MOSFETs using high-HfO2 gate dielectrics achieve very low gate leakage and higher current density. This positions vertical GaN devices to compete with SiC for 1.2 kV applications once substrate and process technologies mature. However, automotive qualification for 800 V+ and 150 kW traction applications remains under development, with readiness expected toward the end of the decade due to cost and reliability considerations.

The lateral GaN devices segment held 70% share and is forecasted to grow at a CAGR of 16.1% from 2025 to 2034. Lateral GaN devices dominate EV power electronics for OBCs, DC-DC converters, and auxiliary systems up to 650 V. Their AlGaN/GaN HEMT structure on silicon provides high electron mobility and critical field strength, delivering low on-resistance at high blocking voltages compared to silicon.
The medium voltage segment (100-650 V) accounted for a 67% share in 2024 and is projected to grow at a CAGR of 16% through 2034. Mid-voltage GaN devices are widely deployed because most OBCs (400 V today, rising to 800 V) and many DC-DC converters fall within this range. GaN's high-frequency performance directly boosts efficiency and power density in power factor correction and LLC or resonant converter stages in 6.6-19.2 kW OBC systems.
China Gallium Nitride (GaN) EV Charger Market generated USD 73.4 million in 2024. Accounting for nearly two-thirds of global EV sales, China's scale generates the largest addressable market for GaN devices, as every EV requires onboard chargers, DC-DC converters, and compatible charging infrastructure. This production volume positions China far ahead of other regional markets like Japan, South Korea, and India.
Key players in the Global Gallium Nitride (GaN) EV Charger Market include Transphorm, Navitas, Texas Instruments, GaN Systems, EPC, STMicroelectronics, ROHM Semiconductor, Infineon Technologies, Innoscience, and Power Integrations. Companies are strengthening their position by investing in R&D to improve GaN device performance, efficiency, and reliability. Strategic collaborations with automakers and charger manufacturers accelerate adoption. Expanding product portfolios with medium- and high-voltage solutions, securing automotive qualification certifications, and developing integrated modules enhances market penetration. Firms also focus on reducing costs through substrate innovations, scaling production capacity, and optimizing supply chains.
