FIELD: electrical engineering.
SUBSTANCE: self-contained portable inductive battery charging device consists of two units. First unit includes an input connected to a charging device which is connected to a battery which is connected to a DC-DC converter which is connected to the output, and the control microcontroller is connected to a charging device, a battery, a DC-DC converter and a charge indicator. In the second unit, the switch is connected to a DC-AC converter, an AC-DC converter, a primary coil, a control microcontroller which is connected to the synchronizing element. Current / voltage sensor is connected to the primary coil and the control microcontroller. DC-AC converter is connected to the output of the first unit, the AC-DC converter is connected to the input of the first unit.
EFFECT: high mobility of a power supply using the principle of wireless inductive charging, providing its autonomous operation without connection to a power supply network, as well as wider range of charging capabilities of this type of charging device.
