-----------------------------------------------------ABSTRACT----------------------------------------------------In recent years, multilevel inverters have gained much attention in the application areas of medium voltage and high power owing to their various advantages such as lower common mode voltage, lower voltage stress on power switches, lower dv/dt ratio to supply lower harmonic contents ...
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...
A new general cascaded multilevel inverter using developed H-bridges is proposed. The proposed topology requires a lesser number of dc voltage sources and power switches and consists of lower blocking voltage on switches, which results in decreased complexity and total cost of the inverter. These abilities obtained within comparing the proposed topology with the conventional topologies from afo...
In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...
In this paper, a seven level asymmetrical cascaded H-Bridge multilevel inverter in three phase configuration using different level-shifted carrier-based pulse width modulation techniques is discussed. Multilevel inverters have become more popular due to high voltage and high power output applications. Comparable to traditional PWM inverters, multilevel inverters are able to reduced switching lo...
