Abstract: This paper raised design of a kind of linear multi-output direct current (DC) stabilized voltage supply, which was based on fixed type stabilized voltage integrated circuits (ICs), providing multiple fixed DC voltage outputs. EDA software platform, Multisim 10 was used to simulate and analyze the design process of power supply. In allusion to problems in simulation process, this paper raised settling plan to improve the efficiency of the experiment. The test for the prototype has proved that this type of power supply is good in performance, reliable in work, meeting the design requirements of output voltage, output current, stabilized voltage coefficient and output ripple voltage, as well as multi-DC requirements for experimental equipment.
Key words: direct current stabilized voltage supply; multi-output; Multisim10 simulation software
