Patent ID: 8339074

Claim:
A power converter control apparatus connected for use to a multiphase alternating current generator motor including an armature winding and a field winding, comprising: a power conversion unit; and a control device for controlling on/off of switching elements of the power conversion unit, wherein: the power conversion unit includes: a bridge circuit including a switching element for a positive side arm and a switching element for a negative side arm, for controlling energization of the armature winding; and a field circuit for controlling energization of the field winding using a field switching element; the control device includes: B-terminal voltage detection means for detecting a B-terminal voltage generated between a reference potential and a B-terminal which is a power input and output terminal of the multiphase alternating current generator motor; field current detection means for detecting a field current flowing through the field winding; generation voltage control means for controlling the field current so that the B-terminal voltage in the multiphase alternating current generator motor becomes equal to a generation voltage command; generation torque control means for controlling the field current so that a generation torque in the multiphase alternating current generator motor becomes equal to a generation torque command; and control selection means for choosing one of the generation voltage control means and the generation torque control means during generation of power; and the control selection means selects the one of the generation voltage control means and the generation torque control means based on one of a command from an outside and a load of the multiphase alternating current generator motor.
