POWER CONVERTER, X-RAY CT APPARATUS, AND X-RAY IMAGING APPARATUS

摘要

In order to prevent breakage of a power converter, a current which flows into an inverter (3) in the power converter is detected. The inverter (3) is equipped with two or more primary windings in parallel with each other. The current flowing through each of the primary windings is detected by current sensors (17, 6). A control unit (22) determines from the outputs of the current sensors that an abnormality occurs, when current does not flow through any of the primary windings.
