Description

 Wireless charging system (options)

The invention relates to electrical engineering and is aimed at providing the possibility of transmitting electricity to wireless devices - keyboards, computer mice, mobile phones, photo, video, web cameras, PDAs, active RPID tags, wireless remotes and input devices, any other low-power wireless devices. There are known wireless power transmission systems based on the reception of electromagnetic waves from ether (WO 2005069503 07/28/2005 H02 J 17/00, JP 2005537773T 12/08/2005 H02 J 17/00, US 2005077872 04/14/2005 H02 J 17/00, WO 200438890 02.02 .2006 H02 J 17/00, etc.) The closest to the invention can be considered a device for implementing a method for providing emergency power to cellular radiotelephones, comprising: a broadband antenna, a step-up transformer, a rectifier, a voltage comparison unit, a mode switching unit, a drive, a battery, an indication unit and control power terminals radiotelephone.

A broadband antenna receives electromagnetic waves in a wide range, which allows for the accumulation of electricity almost anywhere. In the low-frequency range, it is best in the area of power lines, and in the high-frequency range it is best in case of a thunderstorm, and next to the transmitting station. A step-up transformer is necessary to ensure the operation of rectifier diodes and to provide the charge voltage of the drive, since magnitude of the electrical signal in broadband the antenna is tenths of a volt. Rectified voltage is used to charge the drive, which can be used as a capacitor with low leakage or battery. (RU 2180465 03/10/2002 H02 J 17/00). However, there may be cases in which the electromagnetic field strength is small, since there are no sources of electromagnetic radiation nearby and the field strength is insufficient to ensure recharging the power sources on the side of the charging unit. In this case, the voltage converter circuit itself (step-up transformer and rectifier) does not allow for guaranteed power supply (recharge) in view of the significant losses on them.

The technical result of the invention is to provide guaranteed wireless power and recharge of various devices containing a charging unit made according to the invention.

To achieve this technical result, a wireless charging system is proposed, comprising a narrow-band high-frequency generator with a radiating antenna on the supply side, and a receiving antenna connected to a voltage inverter on the side of the charging unit, the output of which is connected to the input of the charge-discharge controller, which is connected to the battery pack and / or with a block of ionistors, wherein the inverter contains a rectifier and a pulse voltage multiplier at the input, containing “n” stages (where “n”> 2), each of which contains a series-connected first diode, a storage capacitor and a second diode, connected in accordance with the first, as well as a MOS transistor with an induced channel, the drain of which is connected to the gate and to the connection point of the first diode and the storage a capacitor, the connection point of which with the second diode is connected to the source of the MOS transistor with the induced channel of the previous stage, while the free terminals of the first diodes connected together and the free terminals of the second diodes connected together are the input of the voltage pulse multiplier, the output of which is the MOS source - transistor with an induced channel of the last stage and the connection point of the storage capacitor and the second diode of the first stage, and also as an option - wireless a charging system containing a narrow-band high-frequency generator with a radiating antenna on the supply side, and a receiving antenna connected to a voltage inverter on the side of the charging unit, the output of which is connected to the input of the charge-discharge controller, which is connected to the battery pack and / or to the block of ionistors, the inverter contains a rectifier and a pulse voltage multiplier at the input, containing "n" stages (where "n"> 2), each of which contains a first diode, a storage capacitor, and a watt connected in series The second diode is connected in accordance with the first, as well as the first and second field-effect transistors, while the connection point of the first diode and the storage capacitor is connected to the gate of the first field-effect transistor and the drain of the second field-effect transistor, the source of the first field-effect transistor is connected to the gate of the second field-effect transistor, the free terminals of the first cascade diodes are combined, the free terminals of the second cascade diodes are combined and the drains of the first field-effect transistors are connected to them, the source of the second field-effect transistor of the cascade connected to the connection point of the capacitor and the second diode of the next stage, and the source of the second field effect transistor of the last stage and the connection point the capacitor and the second diode of the first stage are the output of the pulse voltage multiplier, the input of which is the interconnected free terminals of the first diodes and, respectively, interconnected free terminals of the second diodes.

Figure l presents a General structural diagram of a wireless charging system.

Figure 2 presents a diagram of a pulse voltage multiplier according to option 1. In Figure 3 presents a diagram of a pulse voltage multiplier according to option 2.

The wireless charging system includes a supply side 1, on which there is a narrow-band high-frequency generator 2 and a radiating antenna 3, as well as a charging unit 4 containing a receiving antenna 5, a voltage inverter containing a rectifier 6 and a pulse voltage multiplier 7, a charge-discharge controller 8, block batteries 9 and the block of ionistors 10.

Pulse multiplier of Embodiment 1 comprises voltage «n» cascades H 1 -I l n, first diode 12, a storage capacitor 13, a second diode 14 and the MOS - induced channel transistor 15.

The pulse voltage multiplier according to option 2 contains "n" stages 1O 1 -Io n , the first diode 17, the storage capacitor 18, the second diode 19, the first and second field effect transistors 20 and 21.

The wireless charging system according to the invention operates as follows.

On the supply side 1, a narrow-band high-frequency generator 2, using a radiating antenna 3, emits electromagnetic waves of a certain frequency ω. These waves induce in the receiving antenna 5 of the charging unit 4 a variable EMF of frequency ω and amplitude, depending on the distance to the emitter. An inverter containing a rectifier 6 and a pulse voltage multiplier 7 must ensure that the AC voltage is converted to a constant (slowly changing) or pulse voltage, which should not be lower than the threshold level due to the specific design of the charge-discharge controller 8 and the used battery pack 9 and the block of ionistors 10. The charge-discharge controller 8 is a standard element used in modern mobile devices. It serves to optimize the charge-discharge mode of batteries and ionistors (supporting the necessary voltages and currents, preventing a full discharge), switching the load on charged batteries and ionistors to support the required supply voltage (for example, in start-up mode), disconnecting elements that are located from the load in charging mode, etc.

The pulse voltage multiplier according to option 1 operates as follows. The input voltage Viп charges parallel-connected capacitors 13 through diodes 12 and 14, which prevent the discharge of capacitors 13 through the input voltage circuit. MOSFETs with induced channel 15 are used for sequentially combining capacitors 13 into an outgoing voltage circuit Vout. At the beginning of the process of charging the capacitors 13, the voltage Vi at the gate of the MOS transistors with the induced channel 15 is small, the resistance of the channel of the transistors is large. Charging capacitors 13 will occur faster than discharge through outgoing circuit (while the equivalent resistance of the transistor channel and the load is greater than the resistance of the diodes). When a certain VoI voltage is reached at the gate of the transistors, the discharge through the outgoing circuit occurs faster than charging the capacitors 13. Thus, self-oscillations with an outgoing voltage close to Vol * N are established. The shape and frequency of the pulses of the outgoing voltage depend on the characteristics of the load, transistors and diodes, capacitors.

The pulse voltage multiplier according to option 2 operates as follows.

The input voltage Viп charges parallel-connected capacitors 18 through diodes 12 and 14, which prevent the discharge of capacitors 18 through the input voltage circuit. Field effect transistors 20 and 21 are used for sequentially combining capacitors 18 into an outgoing voltage circuit Vout. While the capacitors 18 are not charged, the voltage Vi at the gate of the p-type transistors 20 is less than the cut-off voltage ViI, the transistors are in the on state. The p-type transistors 21, on the other hand, are turned off, since a negative voltage Vo is applied to their gate, which should be less than the cut-off voltage of the VoI transistors. Thus, the outgoing circuit is open. As the capacitors 18 are charging, transistors 20 are turned off, the gate voltage of transistors 21 rises and they turn on. The capacitors 18 are combined in a serial circuit, and begin to discharge through the load circuit with an initial voltage Vout, a multiple of N. As soon as the voltage on the capacitors 18 drops to a certain level, the transistors 20 and 21 are turned off, and the process of charging the capacitors 18 through the circuit incoming voltage is repeated. The shape and frequency of the outgoing voltage pulses depend on the characteristics of the load, transistors and diodes, capacitor capacitances and are oscillations near Vout. The presence of a narrow-band high-frequency generator on the supply side allows uninterrupted power supply (charge of the supply elements) regardless of the presence or absence of other sources of electromagnetic radiation.

For example, you can consider the operation of the device when powered by a wireless computer mouse. To ensure the operation of the mouse, it is necessary to use power, which is currently supplied by batteries, the operating life of which is quite small. In the present invention, the batteries are replaced with the charger and narrowband high frequency generator described above. A generator connected either to a computer or directly to the electric network will ensure the operation of all computer mice equipped with a charger in the area of its field. In this case, the generator can turn off for a certain time, since the energy stored in the batteries and / or ionistors is enough for the autonomous work of mice. In addition, recharging can be carried out by means of relatively low-power background electromagnetic fields, since the charger is equipped with a broadband antenna and a pulse voltage multiplier, which will increase the battery life of wireless devices.
