<P>PROBLEM TO BE SOLVED: To provide a system which supplies voltages of different levels efficiently. <P>SOLUTION: A motor 22 of a generator-power supply system 20 installed in an aircraft or the like drives a shaft 24. Permanent magnets 26 and 28 rotate with the shaft 24. A three-phase stator winding 30 arranged adjacent to the magnet 26 supplies a current of a low voltage to a customer DC bus 38 through a commutator 32, a filter 34, and a breaker 36. The magnet 28 rotates at a position adjacent to a stator winding 54. The magnet 28 and associated windings 54 and 56 are structured so as to supply a relatively high voltage to a controller 60 and pumps 62, 64 and 66. The stator windings 30 and 54 are mutually connected through a bidirectional DC/DC converter. <P>COPYRIGHT: (C)2010,JPO&INPIT |
