When the wire is detected, the logic control unit controls to stop transmitting. The detection system detects the presence of a load on the opposite side of the wireless transmission unit 2 by means of the fine pedal 8: if there is no load: the transmission is stopped; if there is a load: the logic controls the single secret! The PWM (wave width modulation) signal is outputted by the first and second control pins i, 12 to drive the first and second metal oxide semiconductor field effect transistors 35, 36 in the buck-boost unit 3. By using the pwm signals, the first and second metal oxide semiconductor field effect transistors 35, 36 can be continuously turned on and off at a high frequency, when the second metal oxide semiconductor field effect The transistor 36 is open and the first metal oxide semiconductor field effect transistor 35 is _, since the second metal oxide semiconductor field effect transistor 36 and the end of the battery 9.3 are both connected to form a loop, thereby The electric energy of the battery 93 is made to pass through the inductance 37 of the first-counter-flow prevention device 4 and the buck-boost unit 3 to flow through the second metal oxide semiconductor field effect transistor 3 6 to charge the inductor 37; when the first metal When the oxide semiconductor field effect transistor 35 is on and the second metal oxide semiconductor field effect transistor 36 is off, the secret from the battery 9 3 is after the inductance, and the system is changed to the first The transistor 35 allows the charged inductor 37 to be discharged to the outside through the wireless transmission unit 2. The MOSFET's are turned on-off and on-off by the first and second MOSFETs 35, 36 to charge the inductor 37 and discharge the inductor 37. When there is current (4) without _transmission unit 2 (10) coil, the coil will generate magnetic lines of force, and the opposite side of the electronic product will be converted into current after sensing the magnetic line. 10 M430763 When transmitting, the battery 9 3 is connected to the wireless transmission unit 2, and the first and second metal-oxide-semiconductor field-effect transistors 3 5 and 3 6 in the step-up and step-down unit 3 are boosted (for example, 3.6~4.2 V DC, the boost is about 5V AC; otherwise, the wireless transfer unit 2 to the battery 9 3 is step-down. One of the first and second metal oxide semiconductor field effect transistors 35, 36 is controlled to buck-boost while the other is controlling synchronous rectification.

The incoming electricity will be depressurized by the buck-boost unit 3. The logic control unit 1 can also control the first backflow preventer 4 to be 0FF by transmitting the hold loop i9, and control the second backflow preventer by the control signal outputted by the fifth control pedal 5 of the logic control unit i. 4 a is 〇N, so that the stepped-down power is supplied via the second backflow preventer 4a and the first-supercapacitor 6 for making a surge (preferably via the third backflow preventer 4b) The battery 9 3 of the portable electronic product 9 is, of course, protected by the engraving circuit 92 to limit the charging range of the battery 9 to the pre-_ (for example: (four) direct current), when the battery 9 3 is When fully charged, the protection circuit 92 controls the stop of charging, and if the opposite side of the electronic product detects no load, it will automatically stop discharging (even when discharging, if the battery of the battery is low) When a set value is reached, the discharge will also stop).

The control switch 5 is controlled by the control of the control signal output from the portable electronic product 9 instead of the control switch 5 of the first embodiment. As shown in the figure, the circuit device θ1 of the portable electronic product 9 has a signal output terminal 9 i φ 1 for manual manipulation (for example, pressing a physical button of the portable electronic product 9 or by carrying the electronic product 9 The touch screen outputs a control signal via the signal output terminal 911 of the circuit device 9 1 . In the second embodiment of the present invention, the second node 4 31 of the first backflow preventer 4 is electrically connected to the signal output terminal 9丄i for output by the signal output terminal 91 1 .

The fourth control pin 4 of the logic control unit 亦可 can be further electrically connected to the third control pin 3, that is, the transmitting circuit i 9 shown in the figure. In summary, the wireless charging device of the present portable electronic product is characterized in that the special setting position of the ultra-capacitor and the impedance of the ultra-capacitor are lower than the battery, so that the super-capacitor is charged first when being charged. In order to achieve the supercapacitance to reduce the glitch problem at each charging, it is relatively possible to avoid the cumulative damage caused by charging the battery each time; the backflow prevention effect of the first and second backflow preventers 4, 4 a In order to avoid leakage, it has the same power-saving effect; by lifting and lowering the single-turn system is a kind of lifting and lowering material with synchronous rectification, preferably metal oxidation 12 M430763 semiconductor field effect transistor synchronous rectification (10) SFET Synchronous rectification), in order to increase the efficiency of the buck-boost; the first-to-three anti-current flow preventers 4, 4a, 4b also use the first and second metal-oxide-semiconductor field-effect transistors 44, 45 as a countercurrent It is important to prevent or use it as a paste, so that the power consumption of the guide is lower, so the discharge scale will be higher, thereby improving the wireless transmission power efficiency.
