Comparison of Five Level Active Neutral Point Clamped Derived Converters

摘要

This paper presents a comparative study between two five-level converters. Control strategies and simulation results are presented in order to show the principles that led to the development of these converters. Advantages and disadvantages are presented in view of the power losses in the semiconductor devices and the power conversion efficiency. Experimental results are presented to prove the operation mode of the most recent converter.
