Abstract: An in-vehicle apparatus is provided which is installed in a vehicle including a power supply. The apparatus includes at least one drive circuit that is driven by DC voltage supplied from the power supply, and a positive electrode side line that electrically connects a positive electrode terminal of the power supply and a high-electric potential side electrical path of the drive circuit. A negative electrode terminal of the power supply and a low-electric potential side electrical path of the drive circuit are electrically connected to a body ground of the vehicle. The apparatus includes an auxiliary line that has a first end electrically connected to the positive electrode terminal or the negative electrode terminal and a second end connected to the high-electric potential side electrical path or the body ground, and that is arranged along the positive electrode side line or the body ground.

Abstract: A rotating electrical machine has a rotor having a field winding and a stator having an armature winding. A control device adjusts a field current flowing in the field winding and an armature current flowing in the armature winding. The armature current flowing in the armature winding is expressed by using a current vector having a d-axis current and a q-axis current in a d-q coordinate system. In a case in which the control device increases the d-axis current to generate a magnetic flux in a direction which is opposite to a direction to generate a magnetic flux by a field current, the control device gradually reduces the d-axis current during a predetermined period of time after increasing the d-axis current in the direction opposite to the direction to generate the magnetic flux by the field current.
