MULTI-OUTPUT POWER SUPPLY

摘要

A multi-output power supply including an auxiliary coil and a rectifier diode is provided to comprise a circuit satisfying a cross regulation spec regardless of a load condition of a secondary side terminal of multi-output. A multi-output power supply comprises the followings: a power supply(100) supplying a first power source and a second power source; a first power source switching unit(110) switching a supply of the first power source; a first transformer(120) transforming a voltage according to a result of switching of the first power source switching unit; a first output circuit unit(130) outputting a voltage outputted from a secondary side terminal of the first transformer; a second power source switching unit(140) switching the supply of the second power source; a second transformer(150) transforming a voltage according to a result of switching of the second power source switching unit; and a second output circuit unit(160) outputting a voltage outputted from a secondary side terminal of the second transformer. The first transformer includes a auxiliary coil(122) for a stabilization of the cross regulation. The first power source switching unit includes a rectifier diode.
