With a total of 3 patents to his name, Vithayathil's work has the potential to revolutionize the way AC generators operate.
Latest Patents
Vithayathil's latest patents include a "Brushless AC field system for stable frequency variable speed alternators." This innovative AC generator features a field winding on the rotor that is excited by AC, allowing for the generation of AC at frequencies different from conventional DC excited generators. The system stabilizes the output frequency of the alternator during speed changes by adjusting the AC frequency of the rotor input. Additionally, the design eliminates the need for brushes or slip rings by housing the auxiliary winding on the rotor itself.
Another notable patent is the "Brushless exciterless field system for AC synchronous machines." This invention describes a three-phase AC motor that operates at synchronous speed without requiring an exciter machine or brushes. It includes an internal excitation system that supplies field current through an auxiliary winding on the stator and rotor. The design allows for independent adjustment of the field current, enhancing the machine's versatility for both motoring and generating modes.
