1. An electric machine, comprising:
a power supply;
a wound field synchronous machine with armature windings and field windings; and
a power converter coupled between the power supply and the wound field synchronous machine, the power converter arranged to provide a pulsed operation by providing a pulsed DC current to the field windings, wherein the pulsed DC current is unidirectional.
