PURPOSE:To automate the phase alignment between a power supply and the rotational phase or an electric rotary machine disposed at a turbocharger without applying load to a power part. CONSTITUTION:Without actuating a power part 2 for feeding three-phase power to an electric rotary machine 1, a polarity discrimination signal from a comparator circuit 32 based on the output of the electric rotary machine 1, and a polarity signal generated by the six-step signal of a controller 3 based on a rotational cycle from the position sensor 11 of the electric rotary machine 1 are subjected to phase dislocation detection by a phase dislocation detecting timer 33, and phase correction is executed on the basis of this value. |
