Abstract
An electric generator according to the invention includes a rotor, a stator, a rectifier, and a regulator. The rotor includes a field winding. The stator includes a first and a second three-phase winding, each of which has three output terminals corresponding to respective phases. The rectifier has a specially designed three-layer structure, to which the output terminals of the first and second three-phase windings are separately connected, and works to output two different DC voltages through rectifying outputs of the two three-phase windings. The regulator works to regulate the output voltages through controlling a field current supply to the field winding. With such a structure, the electric generator can reliably produce two different output voltages at the same time. Moreover, compared to existing electric generators producing dual output voltages, the structure of the electric generator is much simplified, thus reducing manufacturing cost and the internal impedance of the electric generator.
