Since the reversible wireless charging and discharging device 100 is in the receiving mode by default, if you want to enter the transmitting mode, you must press the control switch 355 to switch.

If a reversible wireless charging and discharging device 100 wants to wirelessly transmit its own power to another electronic product 5 equipped with a wireless charging device, first press the control switch 355 to make it conductive, and the power of the power storage unit 34 will be turned on. After passing through the control switch 355, it will flow through the third control pin (namely: emission identification control pin) 3513 to allow the logic control unit 351 to recognize that it is currently switched to the emission mode. The power of the power storage unit 34 originally blocked by the first backflow preventer 354, when the control switch 355 is turned on, will turn on the first backflow preventer 354 to allow the power to pass through, and then pass through the buck-boost unit of the buck-boost unit 353 The first MOSFET 3535 is connected to the power pin 3517 of the logic control unit 351 to supply power to the logic control unit 351 . And the second backflow preventer 354a is used to prevent the electric power of the electric storage unit 34 from being recharged.

To achieve the effect of launch hold, so as to be able to maintain the launch state.

The detection pin 3518 of the logic control unit 351 will detect whether there is an electronic product to be charged on the opposite side of the wireless receiving and transmitting unit 352 with an antenna. If not detected, the logic control unit 351 will control the transmission to stop. The detection is by the detection pin 3518 to detect whether there is a load on the opposite side of the wireless receiving and transmitting unit 352, if there is no load: stop transmitting; if there is a load: the logic control unit 1 will be controlled by its first and second pins 3511 and 3512 output PWM (Wave Width Modulation) signals to drive the first and second MOSFETs 3535 and 3536 of the buck-boost unit in the buck-boost unit 353 . By waiting for the PWM signal, the first and second metal oxide semiconductor field effect transistors 3535 and 3536 of the buck-boost unit can be continuously switched on and off at a very high frequency. When the second metal oxide transistor of the buck-boost unit When the semiconductor field effect transistor 3536 is on and the first metal oxide semiconductor field effect transistor 3535 of the buck-boost unit is off, since one end of the second metal oxide semiconductor field effect transistor 3536 of the buck-boost unit and the power storage unit 34 are both Grounded to form a loop, so that the power of the power storage unit 34 can pass through the first backflow preventer 354 and the inductor 3537 of the buck-boost unit 353 to flow through the second metal-oxide-semiconductor field-effect transistor 3536 of the buck-boost unit, Thus, the inductor 3537 is charged; when the first MOSFET 3535 of the buck-boost unit is turned on and the second MOSFET 3536 of the buck-boost unit is turned off, the electricity from the power storage unit 34 is After passing through the inductor 3537 , the first metal-oxide-semiconductor field-effect transistor 3535 of the buck-boost unit is changed, so that the charged inductor 3537 can be discharged to the outside through the wireless receiving and transmitting unit 352 .

In other words, the first and second MOSFETs 3535 and 3536 of the buck-boost unit are one-on-one-off, and one-off-one-on, so as to charge the inductor 3537 and discharge the inductor 3537 . When a current passes through the coil in the wireless receiving and transmitting unit 352 , the coil will generate a magnetic force line, and the electronic product on the opposite side will convert the magnetic force line into a current after sensing the magnetic force line.

When transmitting, from the power storage unit 34 to the wireless receiving and transmitting unit 352, the first and second metal-oxide-semiconductor field-effect transistors 3535, 3536 of the step-up and step-down unit in the step-up and step-down unit 353 passed therebetween are boosted (for example From 3.6-4.2V direct current, the voltage is boosted to about 5V alternating current); on the contrary, from the wireless receiving and transmitting unit 352 to the power storage unit 34 is a step-down.

If one of the first and second MOSFETs 3535 and 3536 of the buck-boost unit controls the buck-boost, the other controls synchronous rectification.

If the reversible wireless charging and discharging device 100 of the present invention is switched to the receiving mode, when the wireless receiving and transmitting unit 352 receives the electricity transmitted from the opposite side, it first supplies power to the logic control unit 351 via the power pin 3517, and then, The received power will be stepped down by the buck-boost unit 353 .

The logic control unit 351 can also control the first backflow preventer 354 to be OFF by the launch hold circuit 3519, and control the second backflow preventer 354a to be ON by the control signal output by the fifth control pin 3515 of the logic control unit 351, Therefore, the reduced voltage is supplied to the power storage unit 34 through the second backflow preventer 354a and the first supercapacitor 356 (preferably through the third backflow preventer 354b) for absorbing surges. Of course, During this period, the charging range of the power storage unit 34 can be limited within a predetermined range (for example: 4-6V direct current) through the protection of the protection circuit 37. When the power storage unit 34 is fully charged, the protection circuit 37 controls to stop charging, And if the electronic product on the opposite side does not detect that there is a load, it will automatically stop discharging (even when discharging, if the power of its own power storage unit is lower than a set value, it will also stop discharging ).

When the logic control unit 351 is switched to the transmission mode, its fourth control pin 3514 will continuously output a transmission hold signal to keep the first backflow preventer 354 ON; when the logic control unit 351 is switched to the reception mode, its first The fifth control pin 15 will continuously output the receive hold signal to keep the second backflow preventer 354a ON.

Please refer to FIG. 6 , which is different from FIG. 3 in that there is no control switch 355 , and the control switch 355 is replaced by the control signal output by the reversible wireless charging and discharging device 100 .

The control circuit 33 of the reversible wireless charging and discharging device 100 has a signal output terminal 343, so that the signal output terminal 343 of the control circuit 33 can output control by pressing a physical button or touching a virtual button on the touch screen. signal. And the second node 35431 of the first backflow preventer 354 is electrically connected to the signal output terminal 343, so that the logic control unit 351 (via the third control pin 3513) can be switched to launch mode.
