A Modified T-Structured Three-level Inverter Configuration Optimized with Respect to PWM Strategy Used for Common Mode Voltage Elimination - 2017

ABSTRACT:

This paper presents an optimized topology for a three - f 3-level inverter with complete elimination of common-mode voltage (CMV). The proposed multilevel inverter (MLI) configuration is realized by modifying a T-structure 3 - f inverter. The proposed configuration is an optimized resolution with respect to the pulse-width modulation strategy used for CMV elimination. The given 3-level inverter structure uses solely 16 power semiconductor switches, that is much under the present configurations. A reduced number of power semiconductor devices leads to a diminished range of driver circuits, less installation house, and low price. Any, thanks to the entire elimination of CMV, the proposed MLI is free from problems such as electromagnetic interference and leakage current with a reduction in filter requirement. The presented topology is additionally compared with other existing topologies to prove its advantage. It is an optimized solution with respect to the dc bus voltage demand and the total voltage rating of the devices or the components employed in the system. Simulation and experimental results are presented to substantiate the potential of the proposed MLI.
