Three Phase Five Level Inverter with SPWM fed from Hybrid Renewable Energy Based Induction Motor Drive

This paper describe the control of a multilevel inverter fed with an Induction motor supplied by a Photovoltaic (PV) panel and wind energy based hybrid generation smart grid. With the increase in number of levels the power quality of multilevel inverter signal may depends. However, during this paper solve the problem of how many number of levels necessary to increase for harmonic reduction. Thus a new push pull converter which is two switch topology will do justice by giving a high power throughout. Three, three level and five-level converters are studied. The harmonics content of the output signals are analyzed. A simplified Pulse Width Modulation (SPWM) technique for a multilevel inverter that supplied an induction motor is developed. The controller equations are such that the SPWM pulses are generated automatically for any number of levels. The Induction Motors are the AC motors and hence from converter, an inverter system is also required to obtain an AC voltage. This inverter is chosen based on its advantages and it is fed to induction motor. In order to maximize the power output the system components of the Hybrid (PV and WIND) system should be optimized. The proposed system performance can be improved by five level inverter and is implemented MATLAB/SIMULINK software for performance of Induction Motor.
