摘要： Leading current or lagging current of an alternator is supplied by a simple structure including short-circuit switch elements. The short-circuit switch elements are connected across output terminals of the alternator three-phase armature windings, and are turned on and off at fixed timings to supply a suitable amount of the leading current to armature windings regardless of the rotational speed. Thus, the leading current can be supplied without phase-leading-capacitors so that the apparatus can be made compact, lightweight and powerful. Even if any of the short-circuit switch elements can not turn off, the battery discharge can be prevented.

摘要： In an on-vehicle alternator, both the magnetic flux variation frequency and maximum flux density are decreased sufficiently to thereby decrease the internal iron loss and thereby realize an increase in the current generation efficiency. The on-vehicle alternator comprises a rotor wherein magnetic pole cores that are polarized by a rotor coil to alternately different polarities are circumferentially disposed on the outer periphery thereof at prescribed equi-angular intervals. A permanent magnet which is embedded within a resin-made retainer body is provided between the magnetic pole cores and has side faces, as viewed circumferentially, which are polarized respectively to the same polarities as those of adjacent respective magnetic pole cores to thereby vary the magnetic flux quantity directed toward stator coils so as to exhibit a circumferential gentle curve. A rectifier is constructed using SiC-MOS transistors so that it is conductive and operative to thereby charge a battery with the current developed in the stator coils only when the alternating current voltages generated in the stator coils have become higher than the battery voltage.

摘要： Reverse current is supplied from a battery to armature coils of a three-phase synchronous power generator, via semiconductor switching devices of a three-phase full-wave rectifier, by controlling the switches. By this control, the reverse current will reduce waveform distortion of armature current of each phase so as to reduce the electromagnetic force pulsation and, therefore, reduce vibration or noise.

摘要： A power-generating voltage outputted from a vehicle synchronous power generator is adjusted to a first voltage for charging a battery under the control of a field current. Further, a leading phase current that leads a phase voltage is supplied to each of multiple armature windings and the field current is supplied to the field winding, whereby the power-generating voltage can be adjusted to a second voltage higher than the first power-generating voltage. Owing to the above construction, a voltage higher than the normal voltage can be generated by supplying each leading phase current from the vehicle synchronous power generator; hence power can be supplied to a high-voltage load based on the generated high voltage.

摘要： A vehicular generator motor performing generator operation and motor operation is disclosed. The generator motor comprises an AC-DC converter means and a switching means. The converter means is composed of a plurality of MOSFETs and connected between each armature coil and a vehicular storage battery. Alternating current produced across the coils is converted into a direct current for charging the battery by the AC-DC converter means in generator operation mode. In motor operation mode, the DC output from the battery is converted into an alternating current for setting up a rotating magnetic field by the converter means, and the battery output is fed to the armature coils. The mode of operation of the MOSFETs is switched between these two modes by the switching means. The rotating field produces a certain phase difference with the magnetic field developed by the rotating magnetic poles. The MOSFETs are made of SiC having a smaller resistivity than that of Si. This ensures a high withstand voltage necessary during power generation. Loss caused by large current flowing in the motor operation mode is reduced. Good driving torque can be obtained.

摘要： An electric power generating device including an induction type electric rotating machine rotating in interlock with an engine comprises an inverter connected at the AC side to and end of an armature winding and at the DC side to an electric power storing device, a detecting means for detecting the quantity of state related to the electric power generating voltage of the induction type electric rotating machine excluding the measured RPM of the induction type electric rotating machine but including the electric power storing voltage of the electric power storing device, and an electric power generation controlling means for maintaining the electric power storing voltage within the preset range by controlling the frequency of the controlling voltage of the inverter based on the quantity of state related to the electric power generating voltage. This electric power generating device can control the electric power generation without using any RPM detecting device for the induction electric machine, and as a result, the composition of the device can be simplified.

摘要： Rectifying elements that constitute a full-wave rectifier of an on-vehicle alternator are constituted by Schottky barrier diodes. The Schottky barrier diode has on one hand the drawback that rectifying characteristics thereof deteriorate due to the heat generation resulting from large avalanche breakdown current that is produced due to surge voltage, with the result that leakage current that occurs when reverse voltage is applied increases. However, according to the present invention, since the surge voltage is absorbed by a voltage regulation diode connected in parallel with the Schottky barrier diode, the voltage regulation diode is broken down when surge voltage has been applied. Accordingly, it does not happen that reverse voltage that exceeds the breakdown voltage of the voltage regulation diode is applied to the Schottky barrier diode. Therefore, it does not happen that the current due to surge voltage exceeding the breakdown voltage thereof flows in the Schottky barrier diode.

摘要： To directly mount a generator to an engine block without causing overheating of the generator or a rectifier, a voltage regulator incorporates a rectifier which employs monocrystalline silicon carbide (SIC) MOS power transistors as semiconductor rectifying devices. This voltage regulator is fixed to housings of a generator, and the housings of the generator are directly mounted to an engine block. In this construction, it is possible to prevent overheating of the rectifier in the voltage regulator as well as of armature windings and a field coil of the generator regardless of an increase in the amount of heat transferred to the generator due to direct mounting.

摘要： A power supply system has a three-phase alternating current generator, a storage battery, and a three-phase rectifying device connected between the alternating current generator and the storage battery. The rectifying device includes three SiC-MOSFETS which are turned on when the corresponding alternating voltage is positive and turned off when the corresponding alternating voltage is negative. A duty control device switches each of the three SiC-MOSFETS on and off according to a selected duty ratio so that the alternating current generator can generate an optimum voltage in proportion to a rotational speed of a rotor of the alternating current generator.
