A Complete Guide to Capacitors
Wind turbines – supercapacitors help to smooth out the intermittent power supplied by the wind. Motors – that drive electric vehicles run off power supplies rated in the hundreds of volts, which means hundreds of supercapacitors connected in series are needed to store the right amount of energy in a typical regenerative brake.

Power Electronics in Small Scale Wind Turbine Systems
At higher wind speeds, the generated power of the wind turbine can go above the limit of the generator or the wind turbine design. When this occurs, small wind turbines use mechanical control or furling to turn the rotor out of the wind resulting in shedding the aerodynamic power or a steep drop in the power curve [ 1, 13 - 16 ].
Which Motor Used In Wind Turbine?
