INDUCTION HEATING AND WIRELESS POWER TRANSMITTING APPARATUS HAVING IMPROVED CONTROL ALGORITHM

摘要

An induction heating and wireless power transmitting apparatus includes: a first working coil portion including first and second working coils that are connected in parallel; a first inverter unit configured to apply a resonant current to the first working coil and the second working coil by performing a switching operation; a first semiconductor switch connected to the first working coil and configured to turn the first working coil on or off; a second semiconductor switch connected to the second working coil and configured to turn the second working coil on or off; and a control unit for configured to detect whether an object is positioned above the first working coil or the second working coil based on controlling the first and second semiconductor switches and the first inverter unit.
