Abstract: The paper presents a wind generator output power appropriately monitored using a closed loop controller engaging the buck-boost competency of Trans qZSI and is fed to grid. The converter getting all benefits of conventional ZSI and exchanges the traditional inverter in the arrangement. Moreover, the Trans qZSI has the exceptional benefits of minimum component count and lower component ratings. The feed forward controller cautiously controls the wind generator output power. It monitors the short circuit duty cycle of inverter using third harmonic injected control technique to create a boosted output. Simulation of the complete circuit is performed on MATLAB and results are discussed. It offers an exclusive voltage regulation by creating proper choice of shoot through duty ratio under variable wind speed. The proposed control system is suitable for transient and steady state operation retaining the preferred level of output.
