Abstract
A DC-DC power converter used in an electromagnetic flowmeter supplies a constant current from a capacitive output to an excitation coil during a measurement portion of the operating cycle. During a relatively longer charging portion of the operating cycle the capacitive output is charged from an unregulated supply. When the unregulated supply voltage of the of the DC-DC converter is less than the regulated output voltage repeated high voltage pulses are generated by the excitation coil to charge the output capacitor.
