Research on Gentle Electric Brakes Using PWM and FET Control circuits on Micro Wind Turbines
a braking system is necessary for micro wind turbines to prevent over revolution,to protect the battery from over charge,and to allow for proper maintenance.Conventional electric brakes cause a large braking torque on the rotor blades and damage from burning of the generator windings by short circuit of the generator output.In this paper through using a PWM electric braking circuit and a FET control circuit a gentle brake can be performed.By changing the parameters of components in the electric brake circuit we can achieve the aim of braking control.From adjust the brake force,the burden placed on a braid,a rotor,dynamo winding,etc.can be eased.
