1. An induction heating device comprising:

  • a plurality of induction heating coils which are disposed adjacent with each other;

    capacitors each of which is connected in series to each of the induction heating coils;

    a plurality of inverters each of which applies a high frequency voltage converted from a DC voltage to each series circuit of the induction heating coil and the capacitor; and

    a control circuit which performs pulse width control of the high frequency voltages, as well as controls the plurality of the inverters so as to align the phase of coil currents flowing through each of the plurality of the induction heating coils,wherein each of the DC voltage is common for the plurality of the inverters.
