Embodiment
As shown in Figure 1, Mobile phone wireless charging device is powered by power supply 1, and electric power management circuit 2 is Boost-Buck circuit, and it is converted to 5V～20V direct current by power supply.The signal that this voltage can obtain according to wireless receiving circuit 6 and coil sample circuit 5 feedbacks by the microprocessor in communication and control circuit 3 carrys out adjusting size; DC power supply after electric power management circuit 2 conversions is to the higher-order of oscillation and power amplification circuit 4 power supplies; Because electric power management circuit 2 can regulation voltage, therefore can be by regulating the output voltage of electric power management circuit 2 control power output on wireless transmission coil 8.Tuning capacitance 7 is the frequency match for oscillating circuit.
Microprocessor in communication and control circuit 3 can produce the high-frequency square-wave signal that frequency range is 100KHz～250KHz, and this signal amplifies by high-frequency oscillating circuits and power amplifier 4.Amplifying coil circuit is comprised of efficient D class power amplifier or bridge-type (half-bridge or full-bridge).The high-frequency square-wave signal that microprocessor in communication and control circuit 3 produces flows to tuning circuit 7 and transmitting coil 8 after high-frequency oscillating circuits and power amplifier 4 amplifications.Wireless transmission coil 8 regulates resonance by shunt capacitance 7, make coil can resonance in the frequency of needs transmitting.
5 pairs of coil currents of coil current sample circuit are sampled and are exported analog voltage, and its voltage is corresponding with coil current value; In microprocessor in communication and control circuit 3, there is A/D sample circuit to read this magnitude of voltage, thus monitoring cable loop current.This processor can be by regulating the output voltage values of electric power management circuit 2 to realize the transmitting power of closed-loop control less radio-frequency coil 8.
Wireless receiving coil 9 and tuning capacitance 10 form receiving circuit and receive the power that wireless transmission coil 8 sends, and then by the bridge rectifier in rectification and voltage stabilizing circuit 11, are converted to 4.2V DC power supply, thereby can charge to battery of mobile phone 13.In addition, the communication chip of the receiving terminal in wireless transceiver circuit 12 can transmit the voltage of receiving terminal and charging current to wireless transmission coil-end by wireless receiving coil 9; Thereby can calculate charge efficiency.
The concrete steps of charging are as follows:
1. wireless transmission coil 8 sends low-power high-frequency signal to wireless receiving coil 9.
2. wireless receiving coil 9 is received after effective high-frequency signal, and by the receiving coil voltage and current obtaining, and self ID signal returns to wireless transmission coil 8.
3. after wireless transmission coil 8 identification ids, confirm as effective charge mobile phone module, thereby get rid of other metals; In addition, wireless transmission coil 8 calculates the coupling efficiency between dispatch coil by the voltage and current information of the wireless receiving coil 9 that obtains; When efficiency is during lower than critical value (as below 35%), to 8 transmittings of wireless receiving coil; When efficiency is more than charging critical point, but during lower than optimum charging scope, can guarantee that mobile phone can be by quick charge by increasing transmitting power.
4. confirm that, after said process, the charge power that wireless transmission coil 8 continues to send optimization is to wireless receiving coil 9.
5. wireless interface receiving end monitoring battery state, after battery has charged; By wireless interface Power Generation Road 12, by wireless receiving coil 9, to transmitting terminal coil 8, send charging ending request.
Reflector complete charge, enters monitoring holding state.
