Title:
POWER SUPPLY DEVICE, MICROWAVE TUBE DEVICE, POWER SUPPLY METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/240909
Kind Code:
A1
Abstract:
In order to suppress the amount of time needed for the start-up of a microwave tube carried out when voltage fed from a power source has decreased, while avoiding increase in scale of a power storage unit, this power supply device includes: a power supply unit that supplies power fed from the power source to the microwave tube that is provided with a cathode, a heater for heating the cathode, an anode, and a collector; a power storage unit that stores the fed power and, if the voltage of the fed power decreases, supplies stored power that is power obtained by the power storing, to the microwave tube; and a power supply switching unit that, if the voltage of the fed power decreases, stops supplying the stored power to the anode and does not stop supplying the stored power to the heater.
