MRT system with a magnetic coil and method for manufacturing a circuit arrangement for switching a coil current |
摘要 |
In a magnetic resonance tomography (MRT) system, a current strength of a coil current is controllable by a plurality of semiconductor power switches as a function of a control signal. The plurality of semiconductor power switches receive the control signal at respective control inputs from a control line. In each of at least two semiconductor power switches of the plurality of semiconductor power switches, a compensation resistance element is connected between the control input and the control line. Resistance values of the compensation resistance elements are different. |
