Abstract: A method of compensating for magnetic flux resulting from variance from a first electric machine to a second electric machine. A magnetic flux change for the first machine is calculated as a function of a flux difference between the first machine and the second machine. Operation of the first machine is controlled using the magnetic flux change.

Abstract: A diesel-electric drive system having a generator mechanically connected to a diesel motor on the rotor side and linked to a voltage source (intermediate) inverter on the stator side. The voltage source inverter is connected to a self-commuting pulse power converter on the generator and on the load side as well as to a brake resistor. The generator has two multiple-phase coil systems which are each electroconductively linked to a self-commuting pulse power converter on the generator side, wherein the second self-commuting pulse power converter on the generator side is switched electrically parallel to the voltage source (intermediate) circuit of the voltage source (intermediate) inverter on the generator side. At least one input phase of the first self-commuting pulse power converter on the generator side is electroconductively linked via a brake resistor to a input phase of the second self-commuting pulse power converter on the generator side.
