Abstract
A control for a DC link power conversion system including a brushless generator having a main generator portion including an armature winding and a rectifier coupled to the armature winding of the main generator portion which converts AC power developed therein into DC power on a DC link comprises a circuit for sensing a parameter of the DC power, a circuit coupled to the sensing circuit for generating an alternating current waveform having a harmonic content dependent upon the sensed DC power parameter and a circuit coupled to the generating circuit for modifying the AC power developed in the main generator armature winding with the alternating current waveform so that the DC power has a certain AC component superimposed thereon.
