Gallium Nitride
A wide-bandgap semiconductor material with a bandgap of approximately 3.4 eV, featuring high electron mobility and a high breakdown electric field, suitable for high-frequency power devices.
Timeline (last 90 days)
Vertical GaN power devices offer higher breakdown field and lower switching losses than silicon, making them suited to high-frequency, high-voltage scenarios and especially well matched to 800V DC architectures.
Traditional silicon-based IGBTs have approached their limits in efficiency and voltage withstand, and wide-bandgap semiconductors (such as silicon carbide and gallium nitride) as well as devices designed specifically for pulsed-power scenarios have become key to the commercialization of fusion power plants.
GaN devices can achieve switching frequencies at the MHz level, while SiC typically operates at 100–300 kHz, giving SiC an irreplaceable advantage in medium-to-large power scenarios above 1 kW.
Gallium nitride (GaN) is a third-generation wide-bandgap semiconductor material that offers higher electron mobility and breakdown voltage compared to traditional silicon-based power devices, enabling operation at higher frequencies.
