1. A remote power supply system for plurality of repeaters distributed over different points of a transmission line, comprising a direct voltage generator at one end of said line, power supply units for said repeaters connected at said points in parallel with said transmission line, each of said power supply units including a d-c to d-c converter having a capacitor for providing voltages to an assigned repeater by charging said capacitor from the voltage of said direct voltage generator for a fixed period of time and then discharging said capacitor for a variable period of time, said variable period of time being determined by the variation of the output voltage of said d-c converter from a reference voltage to provide an efficient constant voltage to said repeater that is equal to the voltages supplied to other repeaters even though the voltage from said voltage generator at the different points of said transmission lines varies.
