PURPOSE:To miniaturize an electric power circuit by dividing plural amplifying elements into plural groups each of which the whole power current passing capacity of the amplifying elements belonging to each group is approximately similar. CONSTITUTION:The patent relates to an electric power supplying system for an amplifier provided with many amplifying elements, such as an amplifier for television community receiving system. Plural amplifying elements 3-5, 9-11 are divided into plural groups 15, 16 each of which the whole power current passing capacity of the amplifying elements belonging to each group is approximately similar. In each group, respective amplifying elements 3-5, 9-11 are connected in parallel with a pair of power terminals 15a, 15b and 16a, 16b assigned to each group and the respective power terminals are connected to each other in series in respective groups 15, 16, which are connected to each other in series to a single electric power circuit 22 through a current supplying circuit 30 and an earth circuit 31. |
