The power semiconductor industry is on the rise, with AI and new energy driving the demand for devices

In 2026, the power semiconductor industry will continue to maintain a high level of prosperity, with resonance formed in the four major fields of AI computing power, energy storage, new energy vehicles, and industrial automation, continuously driving the market demand for core power devices such as MOSFETs and IGBTs. As a core incremental scenario, AI server power supply imposes strict requirements on key parameters such as the on resistance Rds, gate charge Qg, and switching loss of power MOS. The market supply of high-frequency and high-efficiency power devices is tight and in short supply.

On the supply side, overseas leaders STMicroelectronics and Infineon continue to increase their power device quotations based on their advantageous products. Domestic manufacturers such as Yangjie Technology, Shilanwei, and Xinjieneng are seizing the market window period, continuously iterating automotive grade and industrial grade power device products, accelerating product performance upgrades and customer introductions. The energy storage industry is rapidly exploding, and BMS battery management systems require a large number of power switch devices. Applications such as new energy vehicle electronic control and vehicle lighting continue to release incremental space, jointly expanding the boundaries of the power semiconductor market.

The development of the industry also faces practical challenges. The entry threshold for high-end automotive grade power devices is high, and the reliability certification process is lengthy. Domestic devices need to go through massive scenarios for long-term verification, and customer certification breakthroughs are difficult. Power semiconductors are different from logic chips in that they do not rely on advanced manufacturing processes. Their core competitiveness lies in the comprehensive capabilities of mature wafer processes, device chip design, and advanced packaging technologies. Compared to the advanced logic chip track, the localization path of power semiconductors is clearer, and it is a highly promising track for the independent substitution process of the domestic semiconductor industry chain.
