Abstract

In an electromagnetic induction type supply side charger according to the present invention, a smoothing condenser and resonant coils, which are both relatively heavy or bulky, among electric/electronic devices which constitute a power conversion circuit formed on a power circuit board housed in a housing of the supply side charger, are secured to a cooling duct secured to the housing.

Claims

1. An electromagnetic induction type supply side charging apparatus in which a power circuit board on which a power conversion circuit is formed to convert the AC of a power source into a high frequency AC is provided in a housing, so that the electric power obtained from the power source AC is supplied in an electromagnetic induction system, wherein among electric/electronic devices which constitute the power conversion circuit, one or more electric/electronic device or devices which is or are relatively heavy or bulky is or are separately secured to at least one of the housing and a structure body secured thereto without being directly mounted to the power circuit board.

2. An electromagnetic induction type supply side charging apparatus according to claim 1, wherein said electric/electronic device is a smoothing condenser provided in a rectifying/power factor improving circuit of the power conversion circuit or a resonant coil provided in a resonant converter of the power conversion circuit.

3. An electromagnetic induction type supply side charging apparatus according to claim 2, wherein said smoothing condenser is made of a single condenser.

4. An electromagnetic induction type supply side charging apparatus according to claim 3, wherein said structure body is a cooling duct in the form of a rectangular tube, so that said power circuit board is provided on a front surface of the cooling duct and said smoothing condenser and the resonant coil are arranged on a side surface of the cooling duct.

5. An electromagnetic induction type supply side charging apparatus according to claim 4, wherein a charge control circuit board on which a charge control circuit is formed to control the power conversion circuit is arranged on a side surface of the cooling duct opposed to the side on which said smoothing condenser and said resonant coil are arranged.

6. An electromagnetic induction type charging system comprising an electromagnetic induction type supply side charging apparatus according to claim 1, and a receiving side charging apparatus which receives electric power supplied from the supply side charging apparatus in an electromagnetic induction system to charge a battery.

7. An electromagnetic induction type charging system comprising an electromagnetic induction type supply side charging apparatus according to claim 2 and a receiving side charging apparatus which receives electric power supplied from the supply side charging apparatus in an electromagnetic induction system to charge a battery.

8. An electromagnetic induction type charging system comprising an electromagnetic induction type supply side charging apparatus according to claim 3 and a receiving side charging apparatus which receives electric power supplied from the supply side charging apparatus in an electromagnetic induction system to charge a battery.

9. An electromagnetic induction type charging system comprising an electromagnetic induction type supply side charging apparatus according to claim 4 and a receiving side charging apparatus which receives electric power supplied from the supply side charging apparatus in an electromagnetic induction system to charge a battery.

10. An electromagnetic induction type charging system comprising an electromagnetic induction type supply side charging apparatus according to claim 5 and a receiving side charging apparatus which receives electric power supplied from the supply side charging apparatus in an electromagnetic induction system to charge a battery.
