PROJECT TITLE :

Design and Implementation of a Novel Multilevel DC-AC Inverter - 2016

ABSTRACT:

During this paper, a unique multilevel DC-AC inverter is proposed. The proposed multilevel inverter generates seven-level AC output voltage with the acceptable gate signal style. Likewise, the low pass filter is employed to cut back the full harmonic distortion of the sinusoidal output voltage. The switching losses and also the voltage stress across the ability devices will be reduced within the proposed multilevel inverter. The operating principles of the proposed inverter and also the voltage balancing method of input capacitors are discussed. Finally, a prototype multilevel inverter with an input voltage of 400 V, output voltage of 220 Vrms and output power of 2 kW is implemented. The multilevel inverter is controlled with the sinusoidal pulse-width modulation(SPWM) by TMS320LF2407 digital signal processor (DSP). The experimental results show that the most efficiency is ninety six.9percent and the complete load potency is 94.vip.c.
