FIELD: electricity.
SUBSTANCE: wireless charging system for low-power consumers of electrical energy comprises a charging station with an emitter (1), and an electrical energy consumer receiver, which are provided with coils that operate on a feedback basis. The emitter coil is provided with two windings (15, 16), the length of the wire of which is divisible by λ/4, where λ is the wavelength used. The receiver is composed of an oscillating circuit comprising a spiral flat coil (6) having a wire length divisible by λ/4 or λ/2 and being connected in parallel to a tuning capacitor (7), which is connected in series via a controlled rectifier (8) to a storage capacitor (10), to a pulse width modulator (9) and to a controller (11), which is connected to a pulse generator (12) and to a storage battery (14).
EFFECT: high efficiency of the system.
