Abstract: A system for driving one or more electrical currents includes a current driver operable to cause current to flow to the one or more driven electrical elements, a sensor module for sensing a current at the input of the current driver, a compensation module for compensating an input control signal based on the sensed current at the input of the current driver and an optocoupling module having a grounded side connected to an earth ground and a floating side connected to a floating ground. The grounded side receives the compensated control signal and the floating side outputs a floating control signal corresponding to the compensated control signal. An amplification module connected to the floating ground is operable for amplifying the floating control signal outputted from the optocoupling module. The amplified floating control signal further controls the current driver to cause the flow of current to the driven electrical elements.
