PURPOSE:To suppress the fluctuation of the other output when one or more outputs are set to no load state by commonly using a transformer and a controller. CONSTITUTION:A base current is applied to a transistor 50 by the electromotive force induced from a winding 46A to 46B by a DC input, thereby switching the transistor. As a result, AC outputs generated at the windings 46C, 46D are produced as rectified outputs V01, V02, and applied to a controller 12. Here, when the output release input is applied to the control input terminal 100 from a controller 124, a transistor 94 is conducted, and a transistor 92 is interrupted. At this time, the output V01 is affected by the influence of the release of V02, the variation in the voltage occurs at the transient time, but the outputs generated at the output terminals 80A, 80B are stabilized by the operation of a photocoupler 72 and the transistor 50. |
