Dr. Arijit Banerjee from the University of Illinois has developed a system and method for maximum power point tracking (MPPT) in windmill turbine motors. This is a method uses an already disclosed and pursued integrated generator-rectifier system which has one active rectifier and several passive rectifier. Maximum power point tracking (MPPT) relies on using the small active rectifier to control the power flow of the whole system, because passive rectifiers don’t have this power flow control capability. It also reduces bulkiness, simplifies hardware and control schemes and improves efficiency of power electronics switch voltage ratings to achieve ac-dc conversion at medium voltage level.

Benefit
