Performance Evaluation of 3-Phase Five Level Flying Capacitor Multilevel Inverter

Multilevel inverter have become more popular over the years in electric high power application with the promise of less disturbance and reduced harmonic distortion without a transformer. This paper proposes performance evaluation of three phase Flying Capacitor Multilevel Inverter (FCMLI), under various modulating techniques for various loads When the level of Inverter is increased the power quality issues such as Harmonics and the Electromagnetic Interference were decreased. Here the 3-Phase FCMLI is analysing under Sinusoidal Pulse Width Modulation. The Proposed 3-Phase FCMLI scheme is capable of producing two-level to five-level pulse width modulated voltage depending on the modulation range. Simulation tests have been conducted that PODPWM methods provide output with relative low distortion and COPWM provides relatively higher Vrms output voltage for induction motor-load.
