1. Analysis and Performance Evaluation of a Three-phase Three-level Sparse Neutral Point Clamped Converter for Industrial Variable Speed Drives
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This thesis project focuses on the simulation, design, hardware realization, and performance evaluation of a Three-phase Three-level (3-L) Sparse Neutral Point Clamped Converter (SNPCC) for Industrial Variable Speed Drives (VSDs). The basic operating principle of the SNPCC is briefly described based on switching functions. LÄS MER
2. Efficiency Comparison between Two-Level and T-Type Inverter for 800 V Automotive Application
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The falling cost of batteries, along with an increasing need to cut emissions, has spurred significant interest in the electrification of vehicles. In addition, as semiconductor devices have evolved, the research for electric vehicles with higher battery voltage has increased. LÄS MER

4. Investigation of Trench Gate IGBTs in MMC based VSC for HVDC
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The following is a thesis project involving investigation of applicability of trench type IGBTs in present and future VSC based HVDC convertors. The work involves three major sections – theoretical loss evaluation of adoption of Trench technology (both IGBT and BIGT) for HVDC Light® applications, testing the Trench IGBT prototype with existing gate units and finalizing with a hypothesis and a practical solution for unexplained turn-on phenomenon observed during testing.
