ABSTRACT:
A gradient magnetic field power supply includes an amplifier for supplying current to a gradient coil. Between input and output of the amplifier is connected a feedback circuit which feeds a portion of an output current at the output back to the input and has a built-in phase compensating circuit for compensating the phase of the feedback current. The frequency response of the phase compensating circuit is made variable and adjusted to fit variations in the load impedance of the amplifier with time. This ensures optimum phase compensation.
