Abstract
A method for operating a magnetic field generator for a magnetic-inductive flowmeter is disclosed. The method involves setting, at a first reversal time, a target current value as target current and a first target voltage value as target voltage. The first target voltage value is greater than a second target voltage value, and the second target voltage value as target voltage effects the control voltage value of a current regulator voltage in a steady state of the magnetic field generator. The method further involves determining a first switching time. The current between a first reversing time and the first switching time reaches the target current value. A current regulator voltage at the first switching time is greater than a minimum voltage value and less than a control voltage value. At the first switching time, the second target voltage value is then set as the target voltage.
