Abstract
A system, comprising: a power switch; a controller; a transformer having a primary winding and a secondary winding; a first control interface that is coupled between the controller and the primary winding, the first control interface being arranged to: (i) detect an electrical current through the primary winding and (ii) output a fault signal to the controller in response to detecting that the electrical current through the primary winding has crossed a threshold; and a second control interface that is coupled between the secondary winding and the power switch, the second control interface being configured to: (i) provide an electrical current received from the transformer to the power switch, (ii) detect whether an error is present in the operational conditions of the power switch, and (iii) in response to detecting the error, change a level of an electrical current through the secondary winding.
