1. A voltage upconverter circuit, comprising:

  • a voltage source providing a DC source voltage;

    a low-voltage capacitor for holding a stored voltage, the capacitor being connected to a load by a first end;

    a first switch connected between a second end of the capacitor and the voltage source, the switch being responsive to a first control signal for closing and establishing a series connection between the capacitor and the voltage source;

    an inductor in series with a diode connected across the first and second ends of the capacitor, the inductor connected to the second end, and the diode connected to the first end of the capacitor; and

    a second switch connected between the junction of the inductor and diode and ground, the second switch being responsive to a second control signal for opening and closing, causing the capacitor to charge during the times the first and second switches are closed.
