1. An open loop inductive element current control system for an inductor, comprising:

  • a switch connected to said inductive element;

    a control system connected to said switch;

    a current sensing circuit connected to said control system;

    said control system determines a duration of time said switch is in an ON mode from said current sensing circuit;

    a timing circuit connected to said control system, said control system determines a duration of time said switch is in an OFF mode from said timing circuit; and

    a differential voltage circuit connected to said timing circuit.
