PURPOSE:To stably and continuously control various kinds of voltage to be supplied to a traveling-wave tube by using jointly a switching regulator for stabilizing the collector voltage and a series regulator for stabilizing the body voltage. CONSTITUTION:An input power supply 1 is connected to a boosting transformer 2 while connecting its secondary side to the respective rectifying circuits 3-5 for a body power supply, a collector piling-up power supply and a collector main power supply. And the voltage fluctuation of the power supply 1 is detected by a detection circuit 6 while being input into a switching regulator 7 in order to control a rectifying circuit 4 for the collector piling-up power supply as well as to control a series regulator 8 connected to the rectifying circuit 3 for the body power supply while detecting the body voltage by a detecting circuit 9 in order supply the voltage 10 for the body, the voltage 11 for the collector and the voltage 12 for the cathode, to a traveling-wave tube. Accordingly, the respective voltage can be controlled continuously and stably while having no noise generation source and improving responsiveness.
