    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 power converter for an AC generator for motor vehicles for converting a generated voltage of the AC generator driven by an engine into a DC voltage to feed to a battery includes at least either high-side MOS power transistors for connecting an output end of an armature coil which generates the generated voltage of the AC generator with a high potential end of a battery or low-side MOS power transistors for connecting the output end of the armature coil with a low potential end of the battery. The MOS power transistors each has a source region, a well region and a drain region. A high resistance connected with either a parasitic diode on the side connected with the source generated between the source region and well region or a parasitic diode on the side connected with the drain generated between the drain region and well region in parallel is formed in the MOS power transistors. Thereby, it allows blocking a reverse current produced by the parasitic diode and giving a necessary potential to the well region. Further, SiC is used in the MOS power transistors rather than Si.

    摘要: A stator coil of a rotary electric machine includes a three-phase Y-form connection circuit including first windings Y1, Y2 and Y3, which are connected in Y-form, and a three-phase delta-form connection circuit including second windings .increment.x3, .increment.y3 and .increment.z3 which are connected in delta-form, wherein the second windings .increment.x3, .increment.y3 and .increment.z3 are sequentially inserted in slots of a stator core to have a phase difference of 120.degree. therebetween, and each of the first windings Y1, Y2 and Y3 is divided into two windings, and the divided first windings are separately inserted in the slots, in which the second windings .increment.x3, .increment.y3 and .increment.z3 have been inserted, so that the resultant composite voltage vector of each pair of the divided first windings is shifted by 30.degree. in phase from the voltage vector of one of the second windings .increment.x3, .increment.y3 and .increment.z3. By virtue of the foregoing structure of the rotary electric machinery, the number of slots decreases and an electromagnetic noise is reduced, since a magnetic force due to the air gap magnetomotive force distribution becomes substantially constant independently of a rotational position of a rotor.
