Asymmetric multilevel inverters generate high-quality output voltage using the same number of components as symmetric inverters. The main drawback these topologies is that they require many DC sources, and power switches must endure high stress. In this paper, a switched-capacitor sub-module inverter topology proposed to reduce sources stress on asymmetric can 15 levels by two supplies capacito...

A multilevel inverter is capable of generating high-quality stepwise pseudo-sinusoidalvoltage with low THD , applicable to high-power and high-voltage systems. These types of topologiesmay require a large number of switches and power supplies. This leads to much cost, large size, andcomplicated control algorithms. Thus, newer topologies are being proposed to decrease the numberof power electron...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...

A new multilevel inverter (MLI) topology is proposedusing a level doubling network (LDN). The LDN takes the form of a half-bridge inverter to almost double the number of output volt-age levels. The concept (of the proposed LDN) has the capability of self-balancing during positive and negative cycles without any closed-loop control/algorithm, and it does not consume or supply any power. The topo...
