<P>PROBLEM TO BE SOLVED: To provide a power distribution system wherein it is possible to reduce the capacitance of a capacitor and yet stabilize applied voltage to a load. <P>SOLUTION: A mixing unit 7 rectifies alternating-current power from an alternating-current power source 3 at a rectification and conversion unit 6 and thereby converts the power into pulsating power. It mixes direct-current power from a direct-current power source E with the pulsating power and outputs the pulsating power or the mixed power, whichever is higher in voltage value, to a power conversion unit 15 located in a subsequent stage. At the power conversion unit 15, the mixed power of the pulsating power and the direct-current power is converted into direct-current power, which is outputted to a direct-current load through a mixed power distribution pathway L20. <P>COPYRIGHT: (C)2010,JPO&INPIT |
