Core Insights - The global electric vehicle (EV) traction inverter installation reached 7.66 million units in Q2 2025, marking a 19% year-on-year increase, driven by the growth in battery electric vehicle (BEV) sales [2] - BEVs accounted for 52% of the inverter installations, maintaining the largest share, surpassing hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and range-extended electric vehicles (REEVs) [2] Market Performance - BYD and Denso lead the market with shares of 17% and 14% respectively, while Huawei's market share increased from 3% to 4% due to the popularity of BEV and REEV models [5] - Inovance has also established itself among the top five suppliers in the market [5] Semiconductor Application - The penetration rate of silicon carbide (SiC) in inverters rose to 17% in Q2 2025, primarily used in BEVs and gradually expanding to PHEVs and REEVs, with the latter two accounting for nearly 19% of installations, all contributed by Chinese manufacturers [6] - The adoption of SiC in REEVs reached 20%, second only to BEVs at 31%, indicating a growing demand that does not detract from other vehicle types but rather expands the overall inverter market [6] - The demand for inverters in PHEVs, REEVs, and BEVs is predominantly driven by the Chinese market, prompting international semiconductor companies like Infineon to increase their production share in China [6]

TrendForce集邦咨询表示，2024年全球牵引逆变器市场装机量达2,721万台 ， 其中，SiC（碳化硅）逆变 器受惠于Tesla（特斯拉）及中国车厂的采用，渗透率于第四季达16%，为当年度最高，对于竞争激烈的功率半 导体产业是正面讯号。 从逆变器供应端分析，比亚迪于2024年第三季已超越日厂Denso（电装），并于第四季持续稳居 全球市占率最高位置。而第四季最大亮点在于华为受益于新能源车 问界系列的热销，首度成为全球 前五大供应商。目前，中国企业已在前五名席次中占据三席，打破过往欧洲、美国及日本供应商主导的市 场格局。 TrendForce集邦咨询指出，短期内牵引逆变器市场成长仍将依靠中国及欧洲带动，特别是BEV对于牵引 逆变器的需求较其他动力模式更高，突显中国市场的表现将更为关键。尽管2025年可能面临美国"弃电从 油"的潜在风险，但受惠于中国整车市场延续汰旧换新的补贴政策，以及在海外市场的大力布局， 预计牵 引逆变器装机市场仍将维持14%的年增长率 。 备注: [1] 电动车包括油电混合车(HEV)、纯电动车(BEV)、插电混合式电动车(PHEV)、燃料电池车(FCV) Mar. 4, 2025 ...
