“…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 recent years, research on new MLIs has focused on topologies that require a minimal number of switches, diodes, gate drivers and DC sources as the number of voltage levels increases [7][8][9][17][18][19][20][21]. These new topologies try to minimize voltage stress on switches and the number of switches in the current path (losses).…”

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.

In this paper a basic block of novel topology of multilevel inverter is proposed. The proposed approach significantly requires reduced number of dc voltage sources and power switches to attain maximum number of output voltage levels. By connecting basic blocks in series a cascaded multilevel topology is developed. Each block itself is also a multilevel inverter. Analysis of proposed topology is carried out in symmetric as well as asymmetric operating modes. The topology is investigated through computer simulation using MATLAB/Simulink and validated experimentally on prototype in the laboratory.

This paper presents a novel cascaded multilevel inverter structure with reduced devices. This structure is termed as sequential switch cascaded multilevel inverter. The basic asymmetrical hybrid circuit is described and is capable of generating 17 voltage levels. The various modes of deriving 17 levels are explained and the proposed topology is compared with existing topologies in various aspects. Neural network controller can be used to generate the gating pulses. The algorithm can be trained online by using back propagation algorithm and also an algorithm to determine the number of levels, maximum voltage ratings and power loss is explained. The simulation can be done by MATLAB Simulink.
