1. A system for controlling a power converter having an inductive component including a first end and a second end, comprising:

  • a low pass filter for producing a ground-referenced voltage across the inductive component that is proportional to an average DC current flowing through the inductive component, wherein the low pass filter is electrically connected to both the first end and second end of the inductive component through circuit elements capable of passing a DC current at all times during normal operation of controlling the power converter; and

    a control device electrically coupled to the low pass filter for;

    calculating the average DC current through the inductive component using the ground-referenced voltage; and

    controlling the power converter using the calculated average DC current, wherein controlling the power converter comprises one of;

    controlling the power converter for maximizing converter input current,controlling the power converter for maximizing converter input power,controlling the power converter for maximizing converter output current, andcontrolling the power converter for maximizing converter output power.
