INDUCTION HEATING AND WIRELESS POWER TRANSFERRING DEVICE HAVING IMPROVED TARGET DETECTION ALGORITHM

摘要

The present invention relates to an induction heating and wireless power transfer apparatus with improved object detection algorithm. In addition, the induction heating and wireless power transmission apparatus according to an embodiment of the present invention, the first working coil unit including a first and second working coil connected in parallel, a rectifying unit for rectifying the AC power supplied from the power supply unit to the DC power, A first inverter unit and a first working coil configured to receive the rectified DC power from the rectifying unit, perform a switching operation to convert the DC power into a resonance current, and apply a resonance current to at least one of the first and second working coils. A first semiconductor switch connected to the first working coil to turn on or turn off, a second semiconductor switch connected to the second working coil to turn on or off the second working coil, and a first 1 The operation of the inverter unit and the first and second semiconductor switches are respectively controlled to determine whether the object is located above the one of the first and second working coils when the resonance current becomes zero. And a control unit for.
