Abstract
A shaft voltage suppression circuit is used with electrical motors or generators of the type including a field winding supported by a shaft which is movable within bearings, which motor or generator is supplied by way of relatively positive and negative buses with electrical power from a source including an electrical power conversion bridge having controlled rectifiers and uncontrolled rectifiers. The shaft voltage suppression circuit includes a first series combination of a first resistor and a first capacitor connected between the positive bus and a common voltage. A second series combination of a second resistor and a second capacitor is connected between the negative bus and the same common voltage and a unidirectional current conductor is connected in parallel with the second resistor such that there is established a low resistance path for current to pass from the negative bus to the common voltage.
