Abstract
A method and associated apparatus for operating an electrical machine includes providing a brushless excitation system including at least one rectifier having at least one diode. The method also includes providing at least one voltage amplitude limiter assembly including at least one resistor and at least one transient voltage suppressor (TVS) electrically coupled with the at least one resistor to form at least one voltage suppression unit. The method further includes transmitting an electrical signal having a current and a voltage to each voltage suppression unit, the voltage having an amplitude. The method also includes electrically coupling the at least one voltage amplitude limiter assembly to the at least one diode. The method further includes transmitting the electrical signal through the rectifier and the voltage suppression unit such that voltage amplitude excursions of the electrical signal are facilitated to be reduced.
