Abstract
An apparatus for driving electrical loads provided at a vehicle by feeding power to the electrical loads, includes a power source for feeding power to a plurality of the electrical loads provided at a vehicle. The plurality of electrical loads are divided into more than one group. Each of the groups is driven by each of a plurality of load drive circuits by feeding power to each of the load drive circuits from the power source, provided at the vicinity of each of set places in the vehicle at which a group of the electrical loads are concentratedly arranged. A power line is connected to the battery, wherein each of the load drive circuits has a pair of power input terminals, and the power line connected to the battery is branched into two branch power wires. Each of the branch power wires is connected to a power input terminal of each of a first two load drive circuits of the load drive circuits. Another input terminal of each of the first two load drive circuits is connected to a power input terminal of a neighboring load drive circuit by a mutual connection power wire, respectively. One of two power input terminals of one of the neighboring two remaining load drive circuits is connected to one input terminal of the other load drive circuit. The branch power wires, the load drive circuits and the mutual connection power wires compose an electrical connection loop.
