【発明の名称】X線管の回転陽極駆動装置
Document Type and Number:
Japanese Patent JP2752058
Kind Code:
B2
Abstract:
An anode driving apparatus of a rotating anode X-ray tube includes a power source transformer connected to an AC power source, first and second taps, located at the secondary winding of the power source transformer, for outputting first and second AC voltages having the same phase, first and second switching elements respectively connected to the first and second taps and each made up of a solid state relay (SSR), an AC motor having a common terminal commonly connected to the first and second switching elements, a main terminal connected to a 0-voltage terminal of the power source transformer, and a subterminal connected to the 0-voltage terminal of the power source transformer via a phase shift capacitor, and a switching controller for turning on/off the first and second switching controller sequentially and continuously turns on the first and second switching elements, and sequentially applies the first and second AC voltages to the common terminal of the AC motor. When generation of the rotate signal is stopped, the switching controller periodically turns on/off the first switching element, at the same frequency as that of the first AC voltage, to half-wave rectify the first AC voltage, and applies a braking voltage to the common terminal of the AC motor.
