Abstract
A brushless electrical power generating system (100) in accordance with the invention includes an exciter (14) for producing alternating current from an exciter rotor; a rectifier (20) mounted for rotation with the exciter rotor for producing a rectified control current from the AC current; a common mode inductor (112), coupled to the control current, for cancelling common mode noise components within the rectified control current; and a main generator (22), having a rotating field winding (24) mounted on a main generator rotor excited by the control current and producing an alternating current power output from a stator.
