Abstract

A drive circuit for effecting current flow in an inductive circuit comprising a coil the circuit including a power transistor having its emitter collector circuit connected in series with the coil, an input transistor for controlling the power transistor and a resistor for providing a signal representative of the current flowing in the coil. A feed back transistor is supplied with the signal developed across the resistor and provides feed back to the input transistor whereby the mean value of current flowing in the coil will depend upon the magnitude of the input signal applied to the input transistor.
