Abstract
Provided is a control device for an electric generator/motor, which includes an armature winding and a field winding, the control device including: a bridge circuit configured to energize the armature winding; a field circuit configured to energize the field winding; and an energization control unit configured to control the energization of the bridge circuit and the field circuit. The energization control unit is configured to perform, when performing switching between a generation mode and a drive mode in response to an external command to control the electric generator/motor, control on a current supply amount for the field winding, and vector control on a current supply amount for the armature winding so as to compensate for a variation in field current.
