<p>The utility model relates to electrical engineering and is intended to provide guaranteed wireless power supply and charging to various devices. The utility model can be used for wirelessly charging low-power electrical devices (telephones, photo cameras, video cameras, toys, souvenirs) in an apartment, an office, or a public building. The 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 lambda/4, where lambda is the wavelength used, and the receiver is composed of an oscillating circuit comprising a spiral flat coil (6) having a wire length divisible by lambda/4 or lambda/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).</p> |
