Description
- The present invention relates to an electric generator-motor system, particularly for use as a generator and a starter motor in a motor vehicle provided with an internal combustion engine, of the kind defined in the introduction of Claim 1.
- A system of this kind is disclosed in EP-A-260176. In this known system the voltage-boosting means includes a chopper-controlled LC-arrangement and the voltage-reduction means is an independent conventional voltage regulator.
- The object of the invention is to provide an improved generator- motor system of the above-specified kind.
- According to the invention this object is achieved by a system having the features defined in Claim 1.
- Further characteristics and advantages of the present invention will become clear from the detailed description which follows with reference to the appended drawing which is provided by way of non-limiting example and shows the electrical layout of a system according to the invention.
- With reference to the drawing, an electric generator-motor system according to the invention includes a rotary electrical machine, generally indicated 1, which is preferably of the synchronous type and has a three-phase armature whose windings are indicated X, Y and Z. These windings are connected in a star arrangement in the embodiment illustrated and are carried by a conventional stator, not shown.
- The synchronous electrical machine 1 also includes a
rotor 2 carrying field-generator means, preferably constituted by permanent magnets. - A three-phase bridge circuit, generally indicated 3, is connected to the armature windings of the machine 1. The circuit includes six
rectifier diodes 4 each connected in parallel with the collector-emitter path of arespective transistor 5. The bases of the transistors are connected in order to corresponding inputs of apiloting circuit 6 which forms part of an electronic control and operating unit, generally indicated 7. -
Sensors 8 are also connected to thepiloting circuit 6 and are associated in order with the windings X, Y and Z so as to provide electrical signals indicative of the currents flowing in these windings. The sensors may be constituted, for example, by Hall-effect devices. - A speed sensor 9 is also connected to the
piloting circuit 6 and provides electrical signals indicative of the angular velocity of the rotor of the electrical machine 1. - A
capacitor 10 is connected in parallel with the bridge circuit 3. - A transistor, indicated 11, has its collector-emitter path arranged between the bridge circuit 3 and one terminal of an
inductor 12 the other terminal of which is connected to the positive pole of a rechargeable direct-current voltage supply 13. This supply is constituted, for example, by the normal battery of a motor vehicle. - A
diode 14 is connected in parallel with the collector-emitter path of the transistor 11 and has its cathode connected to the bridge circuit 3 and its anode connected to theinductor 12. - The base of the transistor 11 is connected to an output of an
operating circuit 15 included in the electronic control and operating unit 7. - A further transistor, indicated 16, has its collector-emitter path connected between the junction between the
diode 14 and theinductor 12 and earth. The base of this transistor is also connected to an output of theoperating circuit 15 of the electronic unit 7. - A
diode 17 is connected in parallel with the collector-emitter path of thetransistor 16, with its cathode on the side nearest theinductor 12. - A resistor, indicated L in the drawing, represents a generic load connected to the
supply 13. - A shunt resistor, indicated 18, is connected in series with the
battery 13 and the load L. This resistor is also connected to an input of theoperating circuit 15 and is intended to act as a sensor for sensing the current supplied to thebattery 13 and the load L by the motor-generator system in operation. - Finally, two capacitors, indicated 19 and 20, are interconnected in parallel between the positive pole of the
supply 13 and a terminal of theresistor 18. - A sensor for providing the
operating circuit 15 with a signal indicative of the voltage supplied to thebattery 13 by the system (when it is operating as a generator) is indicated 21. This sensor is constituted, for example, by a voltage divider or potentiometer in parallel with the battery. - The generator-motor system described above can conveniently be used as a generator and as a starter motor in a motor vehicle provided with an internal combustion engine. For this use, the
rotor 2 of the electrical machine 1 is connected mechanically to theflywheel 22 of the internal combustion engine by means of adifferential reduction unit 21 which may be of the epicyclic type or the "harmonic drive" type. When the rotor of the electrical machine 1 is acting as the driving part, thereduction unit 21 rotates theflywheel 22 at a considerbaly reduced speed in known manner. When the electrical machine is rotated by the internal combustion engine and is therefore operating as an electrical generator, the reduction unit transmits the drive from theflywheel 22 to the rotor of the electrical machine with a transmission ratio more or less equal to one. - The electronic control and operating unit 7 detects the rate of rotation of the
rotor 2 of the electrical machine 1 in operation by means of a sensor 9 and, by comparing that rate with a pre-established reference, can establish whether the machine is operating as a motor or as a generator and consequently provides for the operation of thecircuits - The operation of the above-described system when it is working as a generator will now be described.
- When it is operating as a generator, the
rotor 2 of the electrical machine 1 is rotated. The electrical machine therefore acts as a generator, in the manner of a normal alternator. - The
piloting circuit 6 keeps thetransistors 5 non-conductive. The three-phase bridge circuit 3 therefore operates as a normal passive rectifier circuit and provides a rectified output voltage which is smoothed by means of thecapacitor 10. - The
operating circuit 15 keeps thetransistor 16 non-conductive and pilots the base of the transistor 11 in an on/off manner with a waveform whose pulse width is modulated (PWM) in dependence on the value of the voltage in the load as detected by means of thedivider 21. Thus, when the transistor 11 is in the "on" condition, a current flows in theinductor 12 and towards thesupply 13 and the load L. Energy is stored in theinductor 12. - When the transistor 11 is in the "off" condition, the
capacitors inductor 12 is recirculated through thediode 17. - The
inductor 12 and thecapacitors supply 13 and the load L. - The voltage output by the bridge 3 varies according to the angular velocity imparted to the
rotor 2 of the electrical machine. When the electrical machine is driven at a speed faster than a certain value, it can supply (downstream of the recitifier) a direct-current voltage higher than the nominal voltage of thebattery 13. In these conditions, thecircuit 15 reduces the voltage delivered to the battery in a similar way to the normal regulation circuits with which alternators used in motor vehicles are provided. However, these regulation circuits regulate the voltage supplied by modifying the current flowing in the field winding normally provided in alternators for use in motor vehicles: these regulation circuits therefore force the alternator to operate in almost short-circuited conditions and the alternator can therefore supply only a fraction of its maximum power. - In the system according to the invention, the voltage supplied by the machine to the battery is not regulated by modifying the field intensity but by choking the voltage supplied (by means of PWM). The machine is thus free to operate at voltages higher than the nominal voltage of the battery and can therefore supply a higher average power than that which can be supplied by a motor-vehicle alternator/regulator unit of similar characteristics, with a consequent net improvement in energy efficiency.
- When it is working as an electric motor, however, the system according to the invention operates as follows.
- The
operating circuit 15 keeps the transistor 11 in the non-conductive condition and pilots thetransistor 16 in an on/off manner by means of a pulsed signal whose pulse width is also modulated (PWM). Thus, when thetransistor 16 is conductive, a current flows in theinductor 12 and in the collector-emitter path of thetransistor 16 and energy is stored in the inductor. When thetransistor 16 is cut off, theinductor 12 is connected to thecapacitor 10 through thediode 14. The energy previously stored in theinductor 12 is discharged into thecapacitor 10 and the voltage at its terminals gradually increases and is brought in successive steps to a value higher than that of thesupply 13. When a predetermined voltage is reached in thecapacitor 10, thepiloting circuit 6 pilots the three pairs oftransistors 5 in an on/off manner in a cyclic sequence with phase differences of 120o, so that the currents which are made to flow in the armature windings X, Y and Z of the electrical machine 1 have waveforms with phase differences of 120o and hence simulate a three-phase current system. The electrical machine 1 therefore acts as a motor and itsrotor 2 starts to rotate. - As stated above, the bridge circuit 3 operates as a simple rectifier bridge when the system is operating as a generator but operates as a three-phase inverter when the system has to operate as a motor. For this purpose, the
piloting circuit 6 may be of the type currently used for piloting so-called brushless motors. - However, the
operating circuit 15 may be a normal integrated PWM modulator circuit easily obtainable commercially. - The functional synergism of some of the components of the system described above is particularly important: the
operating circuit 15, thecapacitor 10, theinductor 12 and the capacitors 19 - 20 form a voltage-boosting circuit when the system is called upon to operate as a motor and a voltage-reduction circuit when the system operates as a generator. The two different operating modes are achieved simply by the different piloting of thetransistors 11 and 16.
