Abstract
An electric power supply apparatus comprises a traveling-wave tube 15 exhibiting partial negative-resistance characteristics and a voltage stabilizing circuit for controlling a voltage control element 12 using an error amplifier 16 and a switch and for supplying stable power to the traveling-wave tube 15. In the apparatus, whether a traveling-wave tube 15 is in positive-resistance operation or negative-resistance operation is detected. In the negative-resistance operation, the control using the error amplifier 16 and the switch S1 is rendered ineffective.
