1. A system comprising:
- a first dynamoelectric device producing a first output and supplying a load;
a second dynamoelectric device producing a second output and supplying the load; and
a control module configured to independently balance the first and second outputs, such that the first and second dynamoelectric devices supply the load in similar proportions, by directly monitoring a first field signal associated with a rotor of the first dynamoelectric device and a second field signal associated with a rotor of the second dynamoelectric device, and adjusting both the first dynamoelectric device and the second dynamoelectric device to balance the first and second outputs.

Abstract
Systems and methods for adjusting outputs of dynamoelectric devices, such as alternators, are provided. The outputs of the dynamoelectric devices may be balanced to facilitate load sharing among the devices. The outputs may be balanced by monitoring field signals associated with the dynamoelectric devices and controlling the field voltages of the devices. The outputs may also be adjusted to supply the load in dissimilar proportions.
