1. A tracking inverter for converting an input voltage to a time-varying output voltage comprising:

  • a voltage converter circuit comprising an inductor, powered by the input voltage and producing an inductor current through the inductor;

    a predetermined output voltage that varies with time;

    a controller, connected to the voltage converter circuit, configured to apply a control signal to the voltage converter circuit;

    the control signal having a duty ratio based on the predetermined output voltage, the time-varying output voltage, the input voltage, a gain factor and the inductor current;

    whereby the voltage converter circuit generates the time-varying output voltage to match the predetermined output voltage; and

    ,wherein;

    the voltage converter circuit is characterized by a set of circuit parameters;

    the duty ratio is given by
