چکیده:

This paper compares a Five-Level Neutral Point Clamped Voltage Source Converter (5L-NPC VSC), a Five-Level Series Connected H-Bridge Voltage Source Converter (5L-SCHB VSC), and a new Five-Level Auxiliary Series Connected HBridge Voltage Source Converter (5L-ASCHB VSC) on the basis of the state-of-the-art 3.3kV, and 1.7kV IGBTs for a 2.3kV Medium Voltage Converter (MVC). To derive specific converter characteristics of the afore mentioned topologies the power semiconductors utilization, the installed switch power, converter losses, the semiconductor loss distribution, efficiency, and the harmonic spectra are discussed in detail. Matlab/Simulink is used as a simulation tool for analysis and comparison.
