Abstract
A sense current generation apparatus constituted of: a main electronically controlled switch arranged to provide a current path for an input current; a sense electronically controlled switch arranged to generate a sense current; a voltage matching circuit arranged to adjust the voltage across the first and second terminals of the sense switch to equal the voltage across the first and second terminals of the main switch, within a predetermined maximum error voltage, such that the sense current is representative of the input current; and a voltage governor arranged to: receive an indication of the voltage across the first and second terminals of the main switch; and responsive to the received voltage indication, adjust the control voltage of the main switch such that the absolute value of the voltage across the terminals thereof is maintained above a predetermined voltage threshold greater than a boundary of the error range.
