<p><P>PROBLEM TO BE SOLVED: To suppress power losses in a power supply unit which sends different currents to a plurality of load circuits. <P>SOLUTION: A first series circuit includes first winding L21 and a first connection part which electrically connects a first load circuit 810 in series to the first winding L21, and electrically connects to the output of a power supply circuit 110. A second series circuit includes second winding L22 which is magnetically coupled in reverse polarity to the first winding L21, a switching circuit S31, and a second connection part which electrically connects a second load circuit 820 in series to the second winding L22 and the switching circuit S31, and electrically connects to the output of the power supply circuit 110 in parallel to the first series circuit. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
