FIELD: electric engineering, possible use for charging mobile phones in autonomous mode.
SUBSTANCE: in autonomous voltage source, diode-capacitor block consists of capacitor, connected in parallel to photo-electric transformer, and two fast action Schottky diodes, first one of which is connected serially between photo-electric transformer and capacitor, and second one - between capacitor and accumulator battery on the side of its positive output.
EFFECT: possible beginning and end of charging of accumulator in sparing mode, and charging of mobile phone may be performed both under sunlight and full darkness; provision of one-sided injection of electric energy from photo-electric transformer to accumulator battery.
