Abstract :
This paper reviews various PWM voltage source inverter (VSI) topologies in the power range (3-8 MW). It also examines and compares practical VSI stack topologies used by VSI manufacturers to achieve a high power medium voltage (MV) converter design. Two commercially available IGBT-based PWM VSI converters are briefly described
