摘要：Emerging Multicell Converters are veryinteresting alternatives for industrial applications.Here, an improved configuration of Double FlyingCapacitor Multicell Converter (I-DFCM) isproposed. The major advantages of proposedconverter is increasing the number of output levelswith reduced number of switches and flyingcapacitors. The conventional configuration ofDFCM converter is modified by additionally addingfour low power switches and one minor dc voltagesource. Added minor voltage source having a smallfraction of voltage rating with main dc-link voltagerating to achieve 27-levels of output voltage. Theproposed converter is controlled by a phase shiftedcarrier pulse width modulation technique.Simulation results are presented to validate theeffectiveness of proposed I-DFCM converter.Furthermore, switching losses and total harmonicdistortion are reduced. The functionalityverification of the proposed 27 level I-DFCMconverter with reduced number of switches is doneusing MATLAB/SIMULINK software.
