Project Description

Topic: Wide Bandgap Semiconductor Power Devices Applied to High-Performance Motor Drives for EVs or UAVs

In a project involving the use of SiC (Silicon Carbide) or GaN (Gallium Nitride) power devices, the tasks typically focus on several key areas:

Circuit Design and Analysis:
This involves designing power electronic circuits, such as inverters, that incorporate SiC or GaN devices. These materials enable the design of smaller and more efficient circuits due to their high efficiency and high-frequency capabilities. Key considerations include parasitic elements, switching frequencies, and thermal management.

Circuit Layouts:
The physical layout of the circuit is critical, especially for high-power applications. Proper layout techniques minimize parasitic inductance and capacitance, which are essential for maintaining performance at high frequencies.

System Testing:
This stage focuses on testing the complete system under various operating conditions to ensure reliability and efficiency.

The adoption of SiC and GaN power devices is increasingly prevalent in applications such as EVs, UAVs, renewable energies, and industrial power supplies, thanks to their superior efficiency, compactness, and high-frequency performance.
