POWER SUPPLY CIRCUIT FOR A COMPUTED TOMOGRAPHY SYSTEM

One or more example embodiments relates to a power supply circuit for a computed tomography system. The power supply circuit comprises a stationary power distributor including an uninterruptible power supply; a co-rotating bias voltage supply, the co-rotating bias voltage supply including a voltage supply input, a bias voltage supply output, and a bias voltage monitoring unit, the bias voltage monitoring unit being configured to activate or to deactivate the bias voltage supply output as a function of an electrical input voltage detected at the voltage supply input, and the bias voltage includes a sensor configure to detect the electrical input voltage at the voltage supply input; and an auxiliary voltage source having a power buffer, the power buffer configured to supply the bias voltage monitoring unit with electrical power for deactivation of the bias voltage supply output.
