  • Another object of the present invention is to provide a non-contact charging system, in which a function of sterilizing a terminal is provided to a non-contact charging pad and causes anions to be generated therefrom, thus enabling sanitary use of the terminal and keeping ambient air nearby thereof fresh.
  • the coils (Pcoil 1 and Pcoil 2 ) are wound around the plate core member ( 131 ) in series or in parallel.
  • FIG. 1 is a block diagram showing the construction of a non-contact charging system according to the present invention.
  • the non-contact charging system includes a battery pack B charged by an induced electromotive force that is generated in a non-contact charger A supplied with power.
  • the non-contact charger A blocks electromagnetic waves caused by Alternating Current (AC) power (110/220 V) input using an electromagnetic wave filter 100 that is connected to the power input terminal of a wireless charging pad, and a primary rectification circuit 110 rectifies the AC power, the electromagnetic waves of which are blocked, to create DC power.
  • a flyback converter 110 ′ contains a transistor, stores power transferred from the primary rectification circuit 110 while the contained transistor is turned on. In contrast, the flyback converter 110 ′ simultaneously applies an input voltage to a gate driver 160 , a central processing unit 180 and an ion generation unit 182 and a driving voltage to a series resonance type converter 120 when the contained transistor is turned off.
  • a current detection unit 170 is interposed between the flyback converter 110 ′ and the series resonance type converter 120 , detects variation in current resulting from the approach of the battery pack B, and outputs a comparison current depending on variation in the current.

  • the current detection unit 170 detects variation in current by comparing the output voltage of the differential amplifier 171 with a predetermined reference voltage, filters out a comparison current depending on the amount of variation in current, and outputs the result.
  • the central processing unit 180 detects the approach of the battery pack B using the comparison current input from the current detection unit 170 , controls the gate drive 160 depending not only on whether a battery pack B approaches but also on the current of a temperature protection circuit unit 183 for stopping the switching of the gate drive 160 when abnormal operation occurs or the temperature of a foreign object placed on the non-contact charging pad exceeds a predetermined temperature. Furthermore, the central processing unit 180 performs the determination of information fed back from a dust and odor sensor 181 and switches the operation mode of the ion generation unit 182 .
  • the gate driver 160 outputs gate signals under the control of the central processing unit 180 , and the series resonance type converter 120 adjusts the waveforms of voltage and current applied to the primary core unit 130 in response to the gate signals input from the gate driver 160 .
  • the gate driver 160 allows two switching devices, which are provided in the series resonance type converter 120 , to be alternately turned on in response to the gate signals output by the control of the central processing unit 180 , and allows the waveforms of the input voltage and current to be adjusted by charging and discharging parallel capacitors coupled to respective switching devices.
  • the series resonance type converter 120 is configured to adjust the waveforms of the voltage and the current applied to the primary core unit 130 by the gate signals.
  • the primary core unit 130 is configured to be switched by the series resonance type converter 120 and, therefore, generate an induced electromotive force.

  • amorphous metal or ferrite material such as Cobalt Co, Iron Fe, Nickel Ni, Boron B or Silicon Si, having high magnetic permeability (>80,000) and an unbroken characteristic.
  • the plate core member 131 is formed in a polygonal shape, it may be formed in either circular or elliptical shapes in addition to the polygonal shape.
  • the central opening 132 is configured such that a function, which is capable both of reducing the amount of material used and of maximizing the area for radiating heat, is provided.
