FIVE LEVEL BOOST SWITCHED-CAPACITOR MULTILEVEL MODULE MULTILEVEL INVERTER TOPOLOGY

In this paper five level boost switched-capacitor multilevel module multilevel inverter topology is presented (BSCMLM MLI). The proposed topology is consisting of two capacitors and single dc source for generation of five inverter output voltage. The switched-capacitor circuit boost up the voltage and balancing the capacitor voltages. This five level topology offers less switching device count with capacitor voltage balancing, it lead to reducing the conduction and switching losses of converter and increase the efficiency of converter. The analyses of switching and conduction losses of suggested topology are presented. This topology is tested with variable frequency multi carrier pulse width modulation (VFMCPWM) technique with different loading conditions are carried out in MATLAB environment.
