Abstract

PURPOSE:To lower a cost of a controller operating a rotary electric machine mounted on a turbocharger rotary shaft either as a generator or as a motor, as required, and to improve energy efficiency. CONSTITUTION:The stator side coil of a generator 13 driven by an engine is made so that it can be switched over either to a star connection or a double star connection by a coil switchover unit 29 and, similarly, a stator side coil of a rotary electric machine 8 is made so that it can be switched over to either the star connection or the double star connection by a winding switchover unit 28. The generator operation side is wound in star connection to increase line output voltage, while the motor operation side is wound in double star connection to decrease line induced voltage. Then, even when the rotary electric machine 8 is operated as a generator and the generator 13 is operated as a motor, impressed voltage on the generator 13 becomes higher than the induced voltage thereof and a boosting circuit inside a power unit 18 in the power feeding route becomes unnecessary. Consequently, a cost can be lowered and energy efficiency can be improved.

The power generated by the rotating electric machine 8 is supplied to the generator 13 via the rectifying circuit 19, the smoothing circuit 20, the boosting circuit 21 and the inverter 22 of the power section 18. The booster circuit 21 is specifically a DC / DC converter and boosts the DC voltage of the smoothing circuit 20. The reason for boosting the voltage is to make the voltage applied to the generator 13 higher than the induced voltage when the generator 13 is operated by a motor. In order to operate the synchronous machine as a motor, it is necessary to apply a voltage higher than its induced voltage as a power source. However, since the synchronous machine used as the rotary electric machine 8 is usually smaller than the synchronous machine used as the generator 13, it does not become higher than the induced voltage when the generator 13 is operated by a motor as it is. Therefore, it is necessary to boost the voltage.

[Operation] The stator winding of the generator driven by the engine can be switched between star connection and double star connection, and the stator of the rotating electric machine that is connected to the rotary shaft of the turbocharger. The side windings should also be switched between star connection and double star connection. The generator operating side is star-connected to increase the line output voltage, and the motor operating side is double star connected to reduce the line induced voltage.
Then, even when the rotating electric machine is operated as the generator and the generator is operated as the motor, the voltage applied to the generator is higher than the induced voltage thereof, so that the booster circuit is unnecessary in the power supply path. Therefore, the cost is reduced and the energy efficiency is improved.

Next, the operation will be described. In a normal operating condition, the generator 13 is operated by star-shaped connection, and the rotating electric machine 8 is rotated only by exhaust energy, or if rotation is insufficient, motor operation is performed by power supply from the generator 13. I'm wondering. When the rotary electric machine 8 is operated by a motor, the controller 17 gives a double star connection. Normally, the rotating electric machine 8 is smaller than the generator 13, and the rotating electric machine 8 is formed into a double star connection and the line-to-line induced voltage is further reduced. It is lower than the line voltage of the machine 13. Therefore, the induced voltage is lower than the applied voltage, and the motor operation can be performed without any problem. The power supply in this case is performed from the generator 13 via the rectifier circuit 25 → smoothing circuit 24 → inverter 23 in the power unit 18, as in the conventional example.

The rotating electric machine 8 is operated as a generator and the generator 13 is operated as a motor. Then, the winding switching units 28 and 29 are controlled so that the rotary electric machine 8 is star-connected and the generator 13 is double star-connected.

In the rotating electric machine 8 connected in a star shape, the line voltage is doubled. On the other hand, in the generator 13 having the double star connection, the line voltage is reduced by half. When the connection is made to have this relationship, the generated voltage from the rotary electric machine 8 is changed to the generator 13
The ratings of the rotary electric machine 8 and the generator 13 are selected in advance so as to be higher than the induced voltage. If you do that,
The induced voltage of the generator 13 becomes lower than the applied voltage,
The motor is operated successfully. Therefore, it is not necessary to interpose a booster circuit in the middle of the power supply path from the rotary electric machine 8 (rectifier circuit 19 → smoothing circuit 20 → inverter 22). When the booster circuit becomes unnecessary, energy is not lost there, and efficiency is improved.

As described above, according to the turbocharger control device with rotating electric machine of the present invention, the stator side winding of the generator can be switched between the star type connection and the double star type connection. Also, the stator side winding of the rotating electric machine can be switched between star connection and double star connection, and the generator operating side is star connected to increase the line output voltage and the motor operating side. Is a double star connection to reduce the induced voltage between lines. Then, even when the rotating electric machine is operated as the generator and the generator is operated as the motor, the voltage applied to the generator is higher than the induced voltage thereof, so that it is not necessary to provide a booster circuit in the power feeding path. Therefore, the cost is reduced and the energy efficiency is improved.
