Abstract
A novel inverter without the chopper for the field circuit was proposed for hybrid-excitation-type synchronous machines. In this inverter, a switch is connected between the neutral point of the armature windings of the machine and the field circuit. The field flux in the machine is increased when the switch is on, and is unchanged when off. By using a circuit simulator, we have clarified that two phase modulation can be used to the inverter when the switch is off.
