Abstract

PURPOSE: To prevent a fault caused in a single component from spreading to the rest of components in the system, by means of installing a diode, connected in series between filter and load circuit, in a circuitry system for feeding the power to the load circuit through the filter from a plurality of power sources.
CONSTITUTION: From a plurality of power sources 1, 2, the power is fed to load circuits 9, 10 through filters 11 to 14, with through type condensers included, respectively. Between the filters 11 to 14 and the load circuits 9, 10, is connected a diode 15 to 18 in series. In this way, even if a short-circuit fault is caused in a through type condenser of the filter 11, the operation of power feed can be continued to the load circuit through a voltage stabilizer 7, 8 because of the diodes 16, 18 being in a state of conduction. In this manner, a single fault caused in a circuit can be prevented from spreading to the rest of the circuits as a system fault, capable of promoting an improvement of the reliability.
