Level-Shifted PWM Techniques Applied to Flying Capacitor Multilevel Inverter

This paper presents the level-shift PWM technique applied to the flying capacitor three-phase five-level inverter. The advantages of the proposed inverter compared to other MLIs, single DC source required, not required more number clamping diodes like diode clamped MLI, less Total Harmonic Distortion value, low power loss, suitable high power applications. The main disadvantage of proposed topology more number of capaciotrs. The proposed topology 22 capacitors are used, each phase 6 capacitors connected across the switches. This paper simulation results verified phase voltage, line voltage, output voltage THD.
