AUTONOMOUS ELECTRICAL POWER SUPPLY SOURCE WITH A RECHARGING FUNCTION USING ONE RECHARGEABLE BATTERY

The invention relates to the field of electrical engineering and can be used for the autonomous supply of electrical energy to electrical consumers. The technical result consists in a manifold increase in an uninterrupted operating time which is equal to the service life of the rechargeable battery using one DC current source. The autonomous power supply source with a recharging function using one rechargeable battery comprises a DC source and an inverter, with an active load being connected in parallel with the output of said inverter via a bridge rectifier. The autonomous power supply source with a recharging function using one rechargeable battery is equipped with a second bridge rectifier, a matching transformer, two electronic transistor switches with a control system, a diode and capacitors, wherein the input of the second bridge rectifier is connected in parallel with the secondary winding of the matching transformer, the primary winding of said matching transformer being connected in series with the output of the inverter and the input of the first bridge rectifier, wherein a capacitor and, via an electronic switch, a load with a capacitor are connected in parallel with the output of said first bridge rectifier, the output of the second bridge rectifier is connected to the capacitor and, via a second electronic switch and a diode, to the DC source, while the control electrodes of the transistor switches are connected to a control circuit.
