Abstract (en)
[origin: EP2890217A1] Provided is a control device for induction heating units which is capable of individually controlling amounts of temperature rise in one side portion and the other side portion of a material to be heated while preventing the occurrence of an abnormal mutual induction phenomenon between two induction heating units. To this end, the control device includes: a master frequency control part that sets an operation frequency of a master inverter, which drives a master C-shaped induction heating unit provided on one side of a material to be heated, so that a phase of an output voltage and a phase of an output current from the master inverter are synchronized; a slave frequency control part that synchronizes an operation frequency of a slave inverter, which drives a slave C-shaped induction heating unit provided on the other side of the material to be heated, with the operation frequency of the master inverter; a slave current phase control part that synchronizes a phase of an output current from the slave inverter with the phase of the output current from the master inverter; a master voltage control part which sets a pulse width of the output voltage from the master inverter; and a slave voltage control part which sets a pulse width of an output voltage from the slave inverter.
