Summary
In 2024, global sales of EV traction inverters are projected to reach 27 million units, representing an annual growth rate of 14% and highlighting continued market expansion. Technological advancements are bolstering inverter performance, driving the growth of the EV market.

The adoption of 800V high-voltage platforms and SiC technology—known for its high voltage resistance, low energy loss, and superior thermal conductivity—has emerged as a key trend. These technologies are particularly appealing for mid-to-high-end vehicle models due to their high efficiency and voltage tolerance. However, cost constraints remain a barrier to their widespread adoption in entry-level models.

Meanwhile, the integration of multi-in-one electric drive systems is advancing, showing potential for weight reduction and efficiency improvements despite ongoing challenges in reliability and cost control.

Additionally, the development and application of power devices and modules serve as critical pillars for the technological upgrade of traction inverters. Looking ahead, China’s localization strategy for semiconductor production is expected to reshape the global power semiconductor landscape.
