Description
Technical field
The present invention provides the method for data low-loss transmission in a kind of high power inductive power-supply supply device, especially refer to when carrying out induction type supply power supply, reduce the power supply unit of the loss of transmission data signals, can make supply module output high-power, and can correctly resolve from the data signals that transmitted by electric module the function of stabilizing control system running.
Background technology
Living environment enters digital Age, various digital products more are full of arround life, digital camera for example, mobile phone, music player (MP3, various portable electronic devices such as MP4), and various portable electronic devices, product is all towards gently, thin, short, little design concept, but as will to reach what can portably use at any time that purpose at first must solve namely be the problem of electricity consumption, the most general general mode is installed rechargeable battery exactly in portable electronic devices, when power drain, can charge again, but everyone has a plurality of portable electronic devices now, each portable electronic devices each has specific compatible charger, and charger is when using, must be plugged into supply socket to connect interface (plug), connector with the other end is plugged into portable electronic devices again, its portable electronic devices is charged, after to be charged the finishing, just the electronic installation on the charger is removed, so need can electrically peg graft just now on the ground that supply socket is arranged because of charger, charging, the place that causes charging is restricted, and outdoorly namely can't charge if be in.
Electronic installation is except charging as another, also must carry out the setting of correlation function or the editor of data, transmit etc., except directly setting by electronic installation, outside the input, some electronic installation (as: music player (MP3, MP4 etc.), digital camera, electronic watch, the portable game machine, the wireless game handgrip, controller etc.) also can't directly set, must be by other electronic product (computer, personal digital assistant etc.) just can carry out function setting, the transmission of data, and general electronic installation is when charging, and can't carry out the transmission of data synchronously, must separately carry out; And the inductive power-supply supply device of releasing on the market at present (or claiming the wireless type charger) is to utilize two coils, one of them is as the feeder ear of emission electric power, another is used as the receiving end that receives electric power and operates, because the energy of wireless power has danger, can heat metal object, principle is as electromagnetic oven, and also influence is recharged object causes damage or fault easily because being heated phenomenon.
And in order to improve present electronic installation when charging, can't transmit data necessary simultaneously, with the disappearance that the target of carrying out electronic installation is identified or the relevant operation of function setting is handled, then this case applicant is once on February 1st, 2011, offer the application of TaiWan, China patent of invention with " method of transfer of data in the high power inductive power-supply supply device ", application case number No. 100103836, and ahead of time for opening in the disclosure of the Invention communique on July 1st, 2011, openly number No. 201123676, case is that this case applicant is by the supply module of power supply unit before this patent of invention, be subjected between the electric module, by the power supply coil with interacted by electric coil, to carry out power supply, the transmission of data signals, and the proportion of goods damageds of transmission capable of reducing power source, the clear transmission of data signals, and has a great fault-tolerant ability, but because of the modulated subcarrier technique modulation circuit that is subjected to electric module after carrying out the modulating data signal, can consume bigger electric current, then when carrying out wireless charging, namely have following disappearance actual, as:
(1) is subjected to the modulated subcarrier technique modulation circuit of electric module, when the modulating data signal, be that electric capacity A 3 front ends from resonant circuit pull high voltage again by MOSFET element conductive ground connection (GND), because so the electric current that the voltage height passes through also can be very big, cause electric power on the coil than high flow rate, (please consult shown in Figure 12 simultaneously so the data wave mode that parses in feeder ear data parser circuitry 13 is significantly sunk, wherein No. 3 downward rapid drawdowns place in waveform stage casing), this also cause down receiving end the data wave mode sink the place be subjected to electric energy power a little less than.
(2) when being subjected to electric modules A to utilize modulated subcarrier technique modulation circuit A 1 to carry out the data signals modulation (seeing also shown in Figure 13), have high voltage, high electric current by MOSFET element A11, cause MOSFET element A11 to burn easily, influence is shortened by the useful life of electric modules A.
(3) be subjected to electric modules A when utilizing modulated subcarrier technique modulation circuit A1 to carry out the data signals modulation, in being subjected to the main power circuit of electric modules A, provide a shortcut by rectifier A2, allow alternating current can not pass through resonant circuit A3 (resonant capacitance), then directly in the phenomenon that is subjected to electric coil A4 to carry out short circuit, can be more clear for the feedback signal that produced by electric coil A4, be easy to identification, so but can cause the power circuit of resonant circuit A3 rear side between the data signals modulation period, to lose power supply capacity fully, cause the situation of of short duration outage, influence is subjected to the power supply output of electric output terminals A 5 unstable between the data signals modulation period.
In the data signals oscillogram of aforementioned Figure 12, the explanation of left side numbering:
Numbering 1-is the control signal of N-type MOSFET element 242.
Numbering 2-is the control signal of N-type MOSFET element 253.
