An electric drive system is disclosed. In one example, the drive system includes a field winding that is electrically coupled to a high voltage bus without any intervening electrical components. Current flow through the field winding is adjusted via adjusting operation of transistors of an inverter so that a magnetic field and electric machine torque may be controlled.
