Classification: CPC H | IPC H

Claim 1:
2. The control circuit according to claim 1, wherein the current detection circuit
is able to generate a second current detection value on a basis of a voltage drop of a resistance component of a second wire existing on a path of a second current flowing through a second phase of the three-phase inverter, the second wire being formed from a material containing copper, or on a basis of a voltage drop of a second resistance that is an on-resistance of an arm of the second phase, and
is able to generate a third current detection value on a basis of a voltage drop of a resistance component of a third wire existing on a path of a third current flowing through a third phase of the three-phase inverter, the third wire being formed from a material containing copper, or on a basis of a voltage drop of a third resistance that is an on-resistance of an arm of the third phase.
