Abstract:
A circuit arrangement for an MRT system and a method for operating an MRT system are disclosed. The circuit arrangement includes a gradient amplifier having a switch-mode output stage, a regulator device, and a modulator connected therebetween in the circuit. To ensure patient safety, a control path is integrated into a drive path of the circuit arrangement or the MRT system provided for driving a gradient coil, the gradient coil being connected to an output of the switch-mode output stage. The control path includes a limiter stage connected downstream of the regulator device, the modulator, the switch-mode output stage and its supply voltage. The limiter stage is connected in the circuit between the regulator device and an input of the modulator, to limit a control signal output by the regulator device and limit the voltage for the gradient coil provided by the switch-mode output stage at its output.

Claim (Index 10):
A method for an MRT system, comprising:\n generating a control signal, via a regulator device of the MRT system, as a function of a difference between a current setpoint value and a current actual value, the current actual value being tapped on an output side of a switch-mode output stage of the MRT system and being output to a limiter stage of the MRT system; defining a current limit setting for the limiter stage, via a control device of the MRT system; limiting the control signal in accordance with the current limit setting defined, and outputting a limited control signal to a modulator of the MRT system, via the limiter stage; generating a modulator signal, via the modulator, as a function of the limited control signal; and specifying a pulse width modulation, for the switch-mode output stage, by the modulator signal to provide a voltage for a gradient coil of the MRT system, wherein a supply voltage of the switch-mode output stage is limited by the current limit setting.
