Wind energy has proved to be the most promising renewable energy source because of its environmental friendly nature. Wind energy can be generated by harnessing the kinetic energy of atmospheric air. The present concern towards wind turbines is to increase the size of turbine in order to harvest more energy and also to reduce cost of per megawatt capacity. This paper proposes a 2-stage power conversion technique. The first stage converts variable DC voltage from wind turbine with the help of universal bridge rectifier into fixed DC voltage using boost converter that operates under the voltage mode control technique. During the next stage, the output from the first stage is fed to a three phase, cascaded multilevel inverter embarrassed by level shift sinusoidal pulse width modulation system with the intention of converting fixed DC to three phase AC which drives three phase AC loads resourcefully. In this method, the overprotective of boost converter as well as the firing pulses for cascaded inverter are generated with a digital controller of field programmable gate array (FPGA).
