Due to the increased Electricity consumption Renewable energy sources such as sun, wind etc., are widely adopted for Electric Power generation. Integration of Renewable energy sources to the grid plays a major role in utilization of energy. Renewable energy sources cannot be directly connected to the grid. Power Electronic converters play a major role in interfacing renewable energy sources to grid or load. The poor quality of voltage and current of a conventional inverter fed induction machine is due to the presence of harmonics and hence there is significant level of energy losses. The Multilevel inverter is used to reduce the harmonics. The inverters with a large number of steps can generate high quality voltage waveforms. The higher levels can follow a voltage reference with accuracy and with the advantage that the generated voltage can be modulated in amplitude instead of pulse-width modulation. This paper discusses photovoltaic (PV) based Multilevel inverter fed Induction Motor topology with involves Pseudo carrier modulation technique as control scheme. The topology offers much less total harmonic distortion. The PV system is verified through simulation in MATLAB/SIMULINK and the FFT spectrums for the outputs are analyzed to study the reduction in the harmonics.
