Design, Implementation, and Validation of a 3-Level GaN-Based T-NPC Power Module for Rapid Prototyping Applications

This thesis, developed at Imperix Ltd, focuses on the design, simulation, implementation, and validation of a GaN-based T-type Neutral Point Clamped (T-NPC) power module. The project aims to expand the Imperix power module portfolio by leveraging the superior properties of GaN HEMTs, such as high switching frequency and low power losses, while maintaining the inherent advantages of three-level topologies.\\Following the definition of the converter specifications, the work details the component selection process, with a specific emphasis on the power switch choice. The core of the hardware development involved the design of the electrical schematics and the PCB layout. PLECS simulations were conducted to validate the design and to develop a robust test setup for the physical prototype. Finally, the manufactured board was tested and validated under various operating conditions and application scenarios to verify its correct operation and identify its performance limits.
