1. An electrical power supply comprising:

  • first coupling means for coupling a direct current input voltage source;

    second coupling means for coupling a regulated voltage to an output load;

    schmitt trigger means having an input terminal, an output terminal, and a control terminal;

    a storage capacitor directly coupled across said output load;

    and non-conduction conditions, comprising a switching regulator means and an oscillator, said switching regulator means having an input terminal coupled to said first coupling means, a control terminal coupled to said output terminal of said schmitt trigger means, and an output terminal coupled to the input of said oscillator, the output of said oscillator coupled to the input of said storage capacitor, a switching amplifier means having conduction for switching said switching amplifier means to either a conduction or non-conduction condition, and for only allowing charging of said storage capacitor during said conduction condition; and

    output voltage detector means having an input terminal coupled to said storage capacitor, and an output terminal coupled to said control terminal of said schmitt trigger means.
