WIRELESS CHARGING SYSTEM (VARIANTS) Russian patent published in 2007 - IPC H02J17/00 H04B1/38 

FIELD: electric engineering.

SUBSTANCE: device contains, on power supply side, a narrowband high frequency generator with emitting antenna, and on the side of charging block, a receiving antenna, voltage inverter, charge-discharge controller, block of accumulators and/or block of super-capacitors, while the inverter contains at its input a rectifier and impulse voltage multiplexer, containing "n" cascades (where "n"≥2), each of which contains serially coupled first diode, accumulating capacitor, and second diode, coupled in accord with first one, and also MOS-transistor with induced channel, drain of which is connected to gate and to connection point of first diode and accumulating capacitor, point of connection of which with second diode is connected to source of MOS-transistor with induced channel of previous cascade, while interconnected free clamps of first diodes and correspondingly interconnected free clamps of second diodes act as input of impulse voltage multiplexer, output of which is the source of MOS-transistor with induced last cascade channel and connection point of accumulating capacitor and second diode of first cascade, and as a variant - device contains on power supply side a narrowband high frequency generator with emitting antenna, and on the side of charging block - receiving antenna, voltage inverter, charge-discharge controller, block of accumulators and/or block of super-capacitors, while inverter contains at input a rectifier and impulse multiplexer of voltage, containing "n" cascades (where "n"≥2), each of which contains serially connected first diode, accumulating capacitor and second diode, enabled in accord with first one, and also first and second field transistors, while point of connection of first diode and accumulating capacitor is connected to gate of first field transistor and to drain of second field transistor, source of first field transistor is connected to gate of second field transistor, while free clamps of first cascade diodes are combined, free clamps of second cascade diodes are combined and drains of first field transistors are connected to them, source of second field transistor of cascade is connected to point of connection of capacitor and second diode of next cascade, and source of second field transistor of last cascade and point of connection of capacitor and second diode of first cascade act as output of impulse multiplexer of voltage, as input of which interconnected free outputs of first diodes and correspondingly interconnected free outputs of second diodes are used.

EFFECT: ensured provision of wireless power and charging to various devices, containing charging block which is made in accordance with the invention.
