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 1):
A circuit arrangement of a system, comprising:\n a gradient coil; a gradient amplifier, the gradient amplifier including\n a switch-mode output stage to provide a voltage for the gradient coil at an output of the switch-mode output stage, \n a regulator device to regulate a current for the gradient coil based upon a current setpoint value and a current actual value, tappable on an output side of the switch-mode output stage, and \n a modulator, electrically connected between the regulator device and the switch-mode output stage, to generate a modulator signal for driving the switch-mode output stage, the modulator signal specifying a pulse width modulation for the switch-mode output stage based upon a control signal output by the regulator device; and \n a circuit arrangement, to drive the gradient coil to ensure patient safety, a control path being integrated into a drive path of the circuit arrangement, the control path including\n a limiter stage, connected downstream of the regulator device, the modulator, the switch-mode output stage, and a supply voltage of the switch-mode output stage, wherein the limiter stage is connected between the regulator device and an input of the modulator, the limiter stage being configured to limit the control signal and being configured to limit the supply voltage of the switch-mode output stage.
