In this paper, a PMSG based wind energy conversion system with various MPPT techniques has been explained. The main aim of the paper is to review the WECS, maximum power point techniques, the behavior of sensor-based and sensorless operation of the wind turbine.  In this paper PMSG based WECS is used due to its gearless and low noise operation. Different types of MPPT techniques are available, those are Hill-Climbing Search (HCS), Optimal Torque Control (OTC), Power Signal Feedback (PSF), and Fuzzy Logic Control (FLC) and Perturb and Observe (P&O) discussed. A sensorless wind turbine is compared to a sensor-based wind turbine. The wind turbine output is mainly depending upon the speed of the blades. When the speed of the wind increases then the speed of the blade increases and vice-versa. The direction of wind flow is not constant all the time, to control those different mechanisms are explained. A gearbox in a wind turbine is generally used for the conversion of the low speed of the rotor into a higher speed. Different types of gearbox ratios will make the generator speed to be increased.
