<p>PURPOSE:To block noise produced in an automobile and to make it possible to use an inverter unit for OA machines by arranging batteries having predetermined capacity, to be connected in parallel, on the input side of a DC power supply for an inverter circuit. CONSTITUTION:Input side of an inverter circuit 40 is connected between the load side of a main switch 36 and the load side of one terminal 32B of a power supply input connector 32, and a battery pack 38 is connected in parallel with the inverter circuit 40 in proximate thereto. The battery pack 38 comprises a breaker 38C and a plurality of batteries 38D and has a predetermined electrical storage capacity. The plurality of batteries 38D serve as filters for blocking electrical noise produced in a generator 11A. According to such arrangement, noise produced in an automobile can be blocked.</p> |
