1. A low-level, high-efficiency, DC-to-DC converter circuit comprising:

  • (a) a source of DC voltage including a solar cell adapted to receive light energy from a laser source by way of an optical fiber;

    (b) an inductance device and a semiconductor switch connected in series with said source;

    (c) a gated or pulse width controlled oscillator connected to the semiconductor switch for turning the semiconductor switch on and off at a predetermined frequency when the gated oscillator is gated on, inducing an AC voltage across the inductance device;

    (d) rectifier means connected to the inductance device for converting the AC voltage back to a DC voltage greater than the DC voltage of said source;

    (e) a pair of output terminals to which a load is to be connected;

    (f) electronic switching means connected in series between the rectifier means and the pair of output terminals; and

    (g) energy storage means coupled in circuit with the electronic switching means for initially storing a voltage therein when the electronic switching means is in a non-conducting state and for providing said stored voltage to the load when the electronic switching means is conducting.
