Abstract

A current source for establishing a relatively constant current through widely differing impedances comprising a voltage potential regulator for adjustably regulating a supplied potential to provide a current to a current controller with a current sensor to supply a signal to the current controller, there being a signal supplied from the signal controller to control the voltage potential regulator. A further current rise time regulator is provided to increase the rise time occurrence provided to a commutated load.
