Abstract

A circuit arrangement is provided for the current supply of a magnetic resonance imaging installation with a radio-frequency shielding cabin and at least one basic field magnet. The arrangement includes a first circuit arranged outside the radio-frequency shielding cabin and configured to generate a DC link voltage from a grid voltage, and a second circuit arranged within the radio-frequency shielding cabin and configured to generate a magnetization current for the basic field magnet from the DC link voltage. This architecture makes it possible to realize a cost-effective solution for an integrated (fixedly installed) modular magnetization current supply.
