MULTI-OUTPUT POWER SUPPLY UNIT AND IMAGE FORMING APPARATUS HAVING POWER SUPPLY UNIT

摘要

PROBLEM TO BE SOLVED: To provide a multiple-output power supply unit which applies a desired voltage to a plurality of loads by simple circuitry.;SOLUTION: The multiple-output power supply unit 50 includes: a first output terminal OUT1 that outputs a second voltage DCLNB corresponding to a first voltage GRID applied to a first load 41 to a second load 45, a first constant voltage element ZD1 that is connected to the first output terminal OUT1, a second constant voltage element ZD2 that is provided between the first constant voltage element ZD1 and a ground, and a second output terminal OUT2 that is connected between the first constant voltage element ZD1 and second constant voltage element ZD2. The second output terminal OUT2 outputs a third voltage DCLNA having a predetermined potential difference from the second voltage DCLNB to a third load 44 so provided as to electrically connect to the second load 45, and receives a load current flowing through the second and third loads 44 and 45 according to the output of the second voltage DCLNB and third voltage DCLNA.;COPYRIGHT: (C)2011,JPO&INPIT
