1. A trickle power supply for generating trickle voltages and currents, said trickle power supply comprising:

  • charge storage means coupled to an unregulated direct current (DC) source for receiving and storing electric charge;

    bidirectionally conducting semiconductor diode means coupled to the charge storage means for enabling said charge storage means to alternately charge and discharge, thereby generating a periodic oscillating waveform having a plurality of alternating charging and discharging profiles;

    voltage reducing means coupled to said charge storage means and said bidirectionally conducting semiconductor diode means for converting said periodic oscillating waveform into a reduced voltage periodic oscillating waveform, andvoltage regulation means coupled to said voltage reducing means for accumulating and converting said reduced periodic oscillating waveform into regulated voltage and current outputs comprising said trickle voltages and currents.
