TrendForce's latest "Global Electric Vehicle Inverter Market Data" shows that global installed capacity for electric vehicle (Note) traction inverters reached 7.66 million units in the second quarter of 2025, a 19% year-over-year increase, driven by growth in pure electric vehicle (BEV) sales.

Analyzed by powertrain mode, BEV installations reached 52%, reclaiming the top spot after the first quarter of 2024 and even surpassing the combined share of hybrid vehicles, including hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and range-extended electric vehicles (REEVs).

Looking at the performance of Tier 1 suppliers, BYD and Denso ranked first and second with market shares of 17% and 14%, respectively. Huawei, benefiting from the strong sales of BEVs and REEVs, saw its share increase from 3% to 4%, a relatively significant growth. The market landscape is increasingly dominated by Chinese companies. In addition to BYD and Huawei, Inovance has also firmly established itself as a top-five supplier.

Regarding the application of power semiconductors in inverters, the penetration rate of silicon carbide (SiC) inverters increased to 17% in the second quarter. These inverters are primarily installed in BEVs but are also gradually expanding into PHEVs and REEVs. The latter two together account for nearly 19% of installed capacity, all of which is contributed by Chinese automakers. The adoption rate of SiC in REEV main drive inverters reached 20%, second only to BEVs at 31%. The surge in REEV installation demand has not squeezed out demand for other powertrains; instead, it has expanded the overall inverter market and become a key driver of SiC adoption.

TrendForce indicates that the SiC inverter market has expanded further as the REEV market matures, gradually reducing the risk of market concentration in the BEV market. The largest markets for PHEVs, REEVs, and BEVs, which have high inverter demand, are in China, driving international semiconductor manufacturers such as Infineon to continuously increase their production share in the Chinese market. Overall, China's mature end-use market for electric vehicles is driving a shift in market power within the entire supply chain, making it more difficult for non-Chinese automakers to catch up.
