<P>PROBLEM TO BE SOLVED: To attain a simple, reliable, low-priced, and efficient power supply system. <P>SOLUTION: This system includes: a rectifier, which rectifies the full waves of three-phase AC or rectifies the half waves and outputs a rectified voltage; a group of batteries, in which a plurality of batteries for outputting the voltage at or under the lower limit value of the output voltage of the rectifier are connected in series; a DC/DC converter, which performs both of step up and step down of the DC voltage; and a DC/DC converter, which only performs the step up of the DC voltage, or a DC/DC converter, which only performs the step down of the DC voltage. It is constituted so that the output voltage of the group of batteries should be applied to the output end of the voltage of the rectifier via a rectifier that is connected in series in the forward direction to the voltage polarity of the group of batteries. <P>COPYRIGHT: (C)2010,JPO&INPIT |
