2. Brief Wind Turbine Description The wind turbine under study belongs to an onshore wind park located in Poland. It has a power of 2300 kW and a diameter of 101 m. Figure 1 shows its major components. A summary of the wind turbine technical specifications is Fig. 1. Main components of the wind turbine [16]. given in Table I. The wind farm .
Wind energy is generated by a wind turbine which converts the kinetic energy of wind into electrical energy. The system mainly depends on speed of the wind to enhance the performance the turbine in mounted on a tall tower. Wind energy conversion system has a wind turbine, permanent magnet synchronous generator and AC-AC converter. As wind .

There are mainly four types dc-dc converters: buck converter, boost converter, buck-boost converter, and flyback converter. The function of buck converter is to step down the input voltage. The function of boost converter, on the other hand, is to step up the input voltage. The function of buck-boost combines the functions of both buck converter
