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 5):
The circuit arrangement of  claim 1 , wherein the limiter stage is connected to a calculation unit, the calculation unit being configured to determine a root mean square value of a resulting voltage for at least one channel of the gradient coil based upon an output signal of the limiter stage and the calculation unit being configured to adjust a limit setting of the limiter stage as a function of at least one first threshold value and the root mean square value of the resulting voltage for the at least one channel.
