L&T Semiconductor Technologies (LTSCT), has announced its first Silicon Carbide (SiC) product platform at SEMICON India 2026. The company has showcased 40 products designed for EV fast charging, traction inverters, microgrids and solid-state transformers. Among the showcased products, a key highlight was the 1200V SiC MOSFET platform for power-conversion applications.
SiC is increasingly adopted in EV power electronics, because it can switch power electronics at higher temperatures and switching frequencies than comparable silicon power devices, particularly silicon IGBTs. In an EV traction inverter, the power semiconductor switches battery DC power into AC power sent to the motor. Increasing the switching and conduction efficiencies of the power devices can increase the overall conversion efficiency.
Higher switching frequencies can also enable engineers to select smaller passive components which can lower the inverter’s size and weight. Additionally, SiC’s high-temperature operation capability contributes to greater thermal management flexibility due to its material and device characteristics. These advantages are relevant to the high-voltage EV architectures such as 800V systems.
By decreasing energy lost as heat during power conversion, higher inverter efficiencies can increase the driving range per charge depending on the overall vehicle design and operating conditions. The difference in range is ultimately limited by the efficiency of the entire powertrain—including batteries, motors, and thermal-management systems—as well as by overall driving conditions.
LTSCT’s SiC platform represents a significant step in the evolution of India’s expanding power-semiconductor ecosystem, especially as EV manufacturers move towards higher-voltage architectures and faster charging. Alongside the SiC platform, the company has showcased a highly integrated BLDC motor controller that is fully designed in India, further expanding its range from individual semiconductor devices to complete power-electronics solutions.
