“…The new topology exhibits better performance, when compared to similar SS MLI topologies [7,17,25,26], in terms of the number of switches, current commutation path and voltage stress on the switches. The validity of the proposed topology is verified by MATLAB R /Simulink R simulations' laboratory-scale experimental results.…”

“…In this section, the proposed topology is compared to the topologies presented in [25,26] and the conventional cascaded H-bridge topology discussed in [26]. Comparisons are made in terms of: (i) the total number of semiconductor devices; (ii) the number of active components in the current path (conduction losses); and (iii) the voltage stress that can be sustained by each switch.…”

Abstract:The increasing integration of large solar PV and wind farms into the power grid has fueled, over the past two decades, growing demands for high-power, high-voltage, utility-scale inverters. Multilevel inverters have emerged as the industry's choice for megawatt-range inverters because of their reduced voltage stress, capability for generating an almost-sinusoidal voltage, built-in redundancy and other benefits. This paper presents a novel switched-source multilevel inverter (SS MLI) architecture. This new inverter shows superior capabilities when compared to existing topologies. It has reduced voltage stress on the semiconductor, uses fewer switches (i.e., reduced size/weight/cost) and exhibits increased efficiency. The proposed SS MLI is comprised of two voltage sources (V 1 , V 2 ) and six switches. It is capable of generating five-level output voltage in symmetric mode (i.e., V 1 = V 2 ) and seven-level output voltage in asymmetric mode (i.e., V 1 = V 2 ). We present simulations results (using MATLAB R /Simulink R ) for five-and seven-level output voltages, and they strongly support the validity of the proposed inverter. These positive results are further supported experimentally using a laboratory prototype.

Interfacing renewable resources with the grid requires a power inverter that meets with the increasing demand of power and its quality related to reduced harmonic distortion. In relation to which multilevel inverters (MLI) have been gaining more consideration for medium voltage high power applications. In this work, a MLI using an embedded type switched boost inverter is studied with their basic performance parameters derived from its basic topology. The model is then simulated using a multicarrier modulation in MATLAB to prove its advantage over the existing topologies.
