<P>PROBLEM TO BE SOLVED: To safely control the optimum feeding number without causing a system failure that halts all rectifiers. <P>SOLUTION: This DC power feeding method for supplying DC power to a load in an interruptible manner by an N number of rectifiers and storage batteries connected in parallel each other generates an output current total voltage signal, in proportion to the current combined with currents in proportion to output currents from the respective rectifiers. At least arbitrary one rectifier in the rectifiers is in a power feed state without determining the halt or resumption of power feed, while other rectifiers within the rectifiers respectively determines whether feeding is halted or resumed based on a signal that indicates the number n of the rectifiers under feeding and the output current total voltage signal. <P>COPYRIGHT: (C)2008,JPO&INPIT |
