| Abstract | Frequency converters are used in wind turbines because they make it possible to apply the variable-speed concept. They also make it possible for wind farm to become active element in the power system. The traditional frequency converter is back-to-back connected two level converters, in which the output voltage has two possible values. However, the output voltage is smoother with a three-level converter, where output voltage has three possible values. This results in smaller harmonics, but on the other hand it has more components and is more complex to control. Multilevel inverter machinery has emerged recently as a very important alternative in the area of high power medium-voltage control and also for improving the total harmonic distortion by reducing the harmonics. Generally, the poor quality of voltage and current of a conventional inverter fed induction machine is obtained due to the presence of harmonics and hence there is a significant level of energy losses. The objective of this paper is to obtain a 3-level output, which is acquire by a three phase three level cascaded multilevel inverter (MLI) fed induction motor drive. This paper compares three phase two level inverter and three level cascaded inverter fed induction motor Drive. |
