Patent JP-H0984263-A (JP)
Title: Power supply for vehicles and method for testing thereof
Inventor: KOZUKA AKIRA
IPC: H02J1/00
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To prevent the increased load on only the power supplies located near a faulty power supply and lessen margins of capacities of the power supplied by lowering a drop characteristic which is used as a reference for the output in general for the power supplies located adjacent to the faulty power supply when any one of a plurality of power supplies becomes faulty. SOLUTION: For example, when a power supply C becomes faulty, a faulty signal to indicate that a power supply other than power supplies B, D gets faulty is input into drop characteristic switching sections of the power supplies B, D which are located adjacent to the power supply C. Then, the drip characteristic switching sections switch a drop characteristic output to an output voltage control section from a standard drop characteristic when all the equipment are healthy to a lower corrected drop characteristic in order to lower an output voltage command compared with the one when all the equipment are healthy. Therefore, the power supplies B, D which are located adjacent to the power supply C are driven to output voltages lower than those of power supplies A, E.  The power supplies B, D which have lower output voltages have smaller partial charge for output current and thereby the responsibilities of these power supplies for supplying power to a load become smaller than when they supply power to the load at normal output voltages.
