Abstract

The Primary function of VSI is to convert fixed DC voltage into variable AC voltage at required voltage and frequency. The diode-clamped multilevel inverter employs clamping diodes and cascaded dc capacitors to produce ac voltage waveforms with multiple levels. The inverter can be generally configured as a three-, four-, or five-level topology, but only the three-level inverter, often known as neutral-point clamped (NPC) inverter, has found wide application in high-power medium-voltage (MV) drives. The dc input voltage of the inverter is normally split by two cascaded dc capacitors, providing a floating neutral point. The control of the neutral-point voltage deviation is also elaborated.The dc supplies are normally obtained from multipulse diode rectifiers. Phase shifted PWM Technique is analyzed and its performance will be compared. Simulation results will be presented to analyze the performance of the PWM techniques. The simulation results will be verified using experimental results
