両の運転に支障を生ずる虞がある。(Problem to be solved by the invention) In the turbocharger with a rotating electric machine as described above,
For example, when power is transmitted from the battery to the rotating electrical machine,
A large current of 0 to 300 A (ampere) will flow, and as a result, the terminal voltage of the battery will drop below 10 V (volts), as shown in the battery load characteristics shown in Figure 2. The voltage supplied to auxiliary equipment that serves as a power source will also be significantly reduced. Therefore, the illuminance of lamps and the like decreases, and the functions of other auxiliary devices decrease, which may impede the operation of the vehicle.

なるという欠点がある。On the other hand, if the generated output of the rotating electric machine driven by the turbine torque is supplied to the battery when the engine is under light load, the high voltage will be large! Due to this, the terminal voltage of the battery increases, and the voltage supplied to the auxiliary equipment connected to the same line also increases, resulting in a disadvantage that the life of the auxiliary equipment is shortened due to the excessive voltage.
本発明はこのような問題に鑑みてなされたものであり、
