Abstract
A current pulse generator for generating current pulses on a conductor of controllable magnitude and duration based on a controlled pulse former. This pulse former is controlled by a controller in communication with a current sensor and operating a magnitude control signal generator as well as the pulse former, the magnitude signal generator also providing a selection signal to the pulse former.
