摘要： A switching type power source device used for magnetic field generation coils for an MRI device in which a switching power sources (9˜11) are constituted by a first and a second multi level PWM inverter (12,13) having a same number of potential levels connected in parallel each other with respect to magnetic field generating coils (6˜8) for the MRI device working as a load as well as a switching control circuit (19) for drive controlling the first and the second multi level PWM inverter (12,13) is constituted to drive control the first and the second multi level PWM inverter (12,13) in a manner to shift the switching phases thereof each other, thereby, ripple components in currents output from the first and the second multi level PWM inverter (12,13) are canceled out each other and a current with a further reduced ripple components as a whole can be supplied to the load (6˜8).

摘要： An X-ray tube apparatus (2) having an anode rotating mechanism for preventing damage of the anode (23) of the X-ray tube apparatus thereby to shorten the X-ray exposure waiting time. When the measured number of revolutions of a rotary anode is determined to be predetermined number from only the impedance or current information on the basis of both voltage information and current information on a stator coil (22) of motor constituent elements for rotating the rotary anode, a DC high voltage outputted from an X-ray high-voltage unit (1) is applied between the anode (23) and a cathode (24) of the X-ray tube apparatus, thus exposing a subject (130) to X-rays and imaging the subject. An X-ray generating device and a radiograph are also disclosed.
