ELEVATING HOME/MOBILE DIGITAL EXPERIENCES WITH HIGH EFFICIENCY AND RELIABILITY

Wide-bandgap power devices, particularly Silicon Carbide (SiC) and Gallium Nitride (GaN), play a critical role in the propulsion and power systems of drones and eVTOLs due to their high-voltage and high-frequency operating capabilities. These technologies significantly improve system performance, efficiency, and reliability.

Efficiency and Range Improvement

SiC MOSFETs, such as 1200V/800A power modules, offer substantially lower switching and conduction losses compared to traditional silicon IGBTs. On 800V platforms, SiC-based inverters can achieve efficiency levels above 98%, increasing flight endurance by 10% to 15% while also supporting ultra-fast charging in less than 15 minutes.

Weight Reduction and Higher Power Density

The high-temperature capability of SiC devices (junction temperature above 175°C) reduces cooling system requirements. When combined with double-sided cooling technology, the overall drivetrain weight can be reduced by 20% to 30%. Compared to conventional systems with a power density of approximately 5 kW/kg, SiC-based solutions can achieve up to 10 kW/kg, significantly improving aircraft design efficiency.

Improved Reliability

With thermal conductivity nearly three times higher than silicon and strong resistance to radiation, SiC power modules ensure stable operation in harsh environments. They can support a service life of up to 100,000 hours, which is approximately five times longer than conventional silicon-based solutions.

These advantages provide greater flexibility in low-altitude aircraft engineering and system design, enabling the implementation of more advanced propulsion architectures. As a result, SiC power devices are becoming increasingly important in high-voltage and high-frequency aviation applications. At the same time, the development of advanced SiC power modules by companies such as BASiC Semiconductor and Aestech is accelerating supply chain localization in the low-altitude economy and supporting broader commercial adoption of next-generation electric aviation systems.
