Abstract
A three-phase alternating-current winding is constructed by forming winding phase portions into a Y connection. The winding phase portions are divided into first and second winding divisions. Outputs from the first winding divisions are rectified and output by a first rectifier, and outputs from the second winding divisions are rectified and output by a second rectifier. In addition, a magnetizing electric current supplied to a field winding is adjusted by a voltage regulator such that the output from the second rectifier becomes constant.
Claims12
An automotive electric power supply assembly comprising:
- a rotor provided with a field winding, said rotor forming a rotating magnetic field when a magnetizing electric current is supplied to said field winding;
- a stator provided with at least one three-phase alternating-current winding constructed by forming three winding phase portions into a Y-connection, said stator being disposed so as to envelop said rotor and to generate an output when said rotating magnetic field is applied thereto;
- and
- a voltage regulating means for adjusting said output from said stator by controlling said magnetizing electric current supplied to said field winding,
- wherein each of said winding phase portions constituting said three-phase alternating-current winding is divided into a plurality of winding divisions, and
- outputs from said winding divisions are simultaneously extracted independently and supplied to different electrical loads.
