From mobile phones and computers to electric cars and solar panels, power electronics are everywhere. The key to power electronics is power semiconductor components, which dominate the efficiency and operating speed of energy conversion. Traditional power semiconductors based on silicon are limited by material properties and have great bottlenecks in energy conversion efficiency and operating frequency. In recent years, gallium nitride (GaN) and silicon carbide (SiC) semiconductor materials have received great attention.
Due to its excellent material properties, it can greatly improve energy conversion efficiency and operating frequency, and is therefore gradually being widely used in applications such as fast charging and electric vehicles. This course will introduce the properties of GaN and SiC semiconductor materials, and briefly introduce the structure and operating principle of GaN and SiC power devices.
