Texas Instruments - Redesign and Optimization of a Three-Level, Three-Phase GaN-Based ANPC Inverter

The demand for high-efficiency and high-power-density inverters is rapidly growing, driven by advancements in power electronics and the adoption of wide-bandgap semiconductors such as Gallium Nitride (GaN). This thesis project focuses on the redesign and optimization of the Texas Instruments TIDA-010210 reference design, a three-level, three-phase Active NeutralPoint Clamped (ANPC) inverter power stage.

The primary goal is to enhance the performance, reliability, and manufacturability of the inverter by implementing optimized switching strategies, PCB layout improvements, and circuit refinements. These optimizations aim to reduce power losses, improve thermal management, and ensure robust operation in high-frequency applications.

The project will include the following key activities:

• Analysis and simulation of the existing ANPC inverter topology, to identify potential areas for efficiency improvements through circuit simulation and performance benchmarking.

• Circuit schematic design of the ANPC inverter using Altium Designer

• PCB layout design, with particular effort in minimizing parasitic elements and ensuring compliance with manufacturability and reliability standards.
