Abstract:
A current sensing circuit for an electronic power converter having an inductor that is not referenced to ground is configured to provide an output signal that is referenced to ground and is proportional to the current flow between the inductor and a load in an electrical power system. The current sensing circuit includes outputs associated with a voltage of the inductor, a current source circuit, a current steering circuit responsive to the voltage outputs and a level shifting circuit.
