Abstract
A machine for generating electricity has an exciter rotor with a plurality of coils, and is associated with a shaft to be driven by a source of rotation. A diode bridge is connected downstream of the exciter rotor to provide a rectifier for an AC current generated by rotation of the exciter rotor. The diode bridge rectifies the AC generated current into DC current, which is passed downstream to windings for a main rotor. A snubber circuit is positioned intermediate said rectifier and said main rotor, said snubber circuit including both a resistor and a capacitor.
