摘要

Circuit arrangement for a current supply of a magnetic resonance imaging facility, a magnetic resonance imaging facility, and a method for operating a magnetic resonance imaging facility The present invention specifies a circuit arrangement for a current supply of a magnetic resonance imaging facility comprising a radio-frequency shielding cabin (3) and at least one basic field magnet (5). This arrangement may additionally include, A first circuit device (1) arranged outside the radio-frequency shielding cabin (3) and generating a DC link voltage (U _Z ) from the grid voltage (U _L ), and - a second circuit device (2) arranged in the radio-frequency shielding cabin (3) for generating a magnetizing current (I _M ) for the basic field magnet (5) from a DC link voltage (U _Z ) The present invention additionally specifies a magnetic resonance imaging facility comprising a circuit arrangement according to the invention, and a method for operating a magnetic resonance imaging facility. This architecture makes it possible to implement cost effective solutions for integrated (fixedly installed) modular magnetizing current supplies.
