Control device for generator-motor and control method for generator-motor
Provided is a control device for a generator-motor including: a control section (111) for controlling a rotary electric machine (12) with use of an inverter (11); and a connection switch section (5) provided between a power source and the inverter, the connection switch section including a change-over contact (51) which is ON/OFF-controllable by the control section and a current reducing resistor (52) which are connected in parallel. The control section performs ON/OFF control of the change-over contact in accordance with drive characteristics of the rotary electric machine so that a drive current that flows when the rotary electric machine operates as a motor falls within a range not exceeding a permissible current value of the rotary electric machine.
