INDUCTION HEATING INVERTER FOR MAGNETIC VESSEL/NON-MAGNETIC VESSEL

摘要

The present invention relates to an induction heating inverter combined with a magnetic / non-magnetic coil, and conventionally, when only one working coil is used and only one working coil is used, only a part of the container is heated, In addition, there is a problem that the EMI filter design which satisfies both the magnetic and non-magnetic modes is difficult, and the price of the resonant capacitor connected in series with the working coil is too high to increase the volume. Accordingly, in the present invention, the divided working coils are connected in parallel in the case of a magnetic body using a relay switch, and in a non-magnetic body, a current flows in only one direction, So that the entire area of the container is heated so as to maximize the use of the working coil, to facilitate the design of the EMI filter, and to lower the price without using the high-voltage capacitor.
