Design, control and analysis of a novel multilevel converter with a reduced switch count
Multilevel converters are used in a wide range of applications, such as drives, energy conversion and distributed generation. This Thesis proposes a new multilevel converter topology that allows increasing the number of output voltage levels with a fewer required power semiconductors than in standard multilevel topologies such as Active Neutral Point Clamped (ANPC), Flying Capacitor Converter (FCC) and Stacked Multicell Converter (SMC). The proposed topology consists of a cascaded connection of basic units called main cells, which are composed of three power switches, one flying capacitor and two output switches for each output phase. In this Thesis, the comparisons are made between the proposed topology and conventional topologies such as ANPC and SMC. Points of comparison include the required number of power switches, voltage stress across the switches, power distribution, capacitors' size and energy storage. To verify the performance of the proposed multilevel topology, extensive simulations and experimental studies were carried out on a 3-phase 5-level converter.
