A simple control strategy for converter current control using diode clamped multilevel inverter (DCMLI) with level shifted carrier PWM modulation in the current control mode for real power injection as well as load compensation has been proposed for wind energy integration to grid . The converter current injected into a distribution system is controlled in accordance with the wind variation and load compensation is performed as an added facility in order to free the source current being fed from the grid at PCC to be free from harmonic distortion, unbalance and low power factor even though...

Voltage Source Inverters(VSI) are widely used in Variable frequency drives, power conditioning equipment, Flexible AC transmission systems(FACTS), custom power devices and uninterruptible power supplies(UPS). The conventional two-level inverter synthesize voltage waveforms with high harmonics current, high dv/dt stress on connected equipment. To improve output wave form quality, the switching frequency has to be raised which causes additional switching losses. For high voltage induction motors, there are several approaches for realizing high voltage and high power inverters. Multi level...
