Abstract
A field current control circuit for an alternating current generator includes a first voltage source and a time lag reduction circuit, which further includes a generator field that is in selective electrical communication with an energy storage component that is in electrical communication with a time lag reduction voltage source. The time lag reduction circuit may include an electronic controller and be a part of an electric drive machine that receives an operator acceleration command and thereby controls the electrical communication between the energy storage component and the generator field of the time lag reduction circuit. When the energy storage component and generator field are in electrical communication, the current passing through the generator field increases from a starting current to a target current with a reduced time lag compared to predecessor generators.
