This article presents a novel control method for multilevel dc–dc flying capacitor converter applications in medium voltage range. Quasi-two-level modulation provides the possibility to obtain low capacitance even below 1 μF, whereas triangular current mode controller part enables achieve zero switching at turn- <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1...

This paper presents a review and analysis of multilevel inverter topologies. Multilevel inverters are most widely used for medium-voltage high-power converter like fans, pumps and material transport drives. In this active area, different inverter topologies, circuits, advantages and drawbacks are discussed. Multilevel Inverter topologies such as diode-clamped, flyingcapacitor, cascaded H-bridge...

This paper presents a detailed harmonic analysis in terms of Total Harmonic Distortion (THD) for different power circuit topologies of multi level inverter fed induction motor drives. The most common multilevel inverter topologies are the neutral-point-clamped inverter (NPC), flying capacitor inverter (FC), and cascaded H-bridge inverter (CHB). This work is to analyze the performance of all the...

Multilevel converters are mainly utilized to synthesize a desired singleor three-phase voltage waveform. The desired output voltage is obtained by combining several separate dc voltage sources. Solar cells, fuel cells, batteries, and ultracapacitors are the most common independent sources used. Multilevel converters have found wide applications in motor drives, static VAR compensators, and unin...
