Abstract
The invention relates to a circuit arrangement for delivering power to coils ( ), which circuit arrangement includes a first and a second coil ( ) a first and a second voltage source ( ) and a first and a second quadrupole switching network ( ), the input ( ) of the first quadrupole switching network ( ) being connected to the first voltage source ( ) and the second voltage source ( ) being connected to at least one terminal ( ) of the second quadrupole switching network ( ). Known switching arrangements have separate voltage sources for each individual power amplifier. In the circuit arrangement in accordance with the invention the two terminals ( ) at the output ( ) of the first quadrupole switching network ( ) are connected, each time via the first and the second coil ( ), respectively, to the two terminals ( ) at the output ( ) of the second quadrupole switching network ( ). It is advantageous that a common voltage source ( ) with a common capacity for delivering power to a plurality of coil systems can thus be provided.
