PROJECT TITLE :

A New Reduced-Component Hybrid Flying Capacitor Multicell Converter - 2017

ABSTRACT:

This paper presents a brand new multicell topology based mostly on flying capacitor (FC) structure suitable for multilevel converters. The proposed topology employs the concept of section-shifted carrier pulse width modulation (PWM) with modified modulating signals to get appropriate PWM signals. The modulation strategy along with all doable switching states are explained. The implementation of the proposed PWM technique is shown by the assistance of illustrating waveforms. To show the benefits of the proposed structure, totally different performance criteria are compared with other FC multicell (FCM) structures. Simulation results are used to any evaluate the potential merits of the proposed topology. It is shown that the proposed structure is superior to other FCM-primarily based structures from completely different standpoints. Specifically, it reduces the number of high-frequency switches, the amount of FCs, and at the identical time improves the quality of output voltage. A laboratory-kind experimental setup is used to validate the modulation strategy and different theoretical findings.
