ABSTRACT:
In an electrical power system of a diesel powered system having at least one diesel-fueled power generation unit, the electrical power system having a synchronous machine including a field winding being coupled to the diesel-fueled power generation unit, a battery for selectively providing a starting current during a starting mode of the electrical power system, and an inverter receiving the starting current for driving the synchronous machine and generating an inverter current, a circuit and method for reducing a voltage being developed across the field winding is described. The circuit includes a current conditioner for conditioning the inverter current and a parallel circuit interposed between the inverter and the current conditioner comprising a first branch including a resistance and a second branch including the field winding of the synchronous machine so that the parallel circuit is isolated from a voltage developed across the current conditioner during cranking.
