Title:
INDUCTIVE HEATING DEVICE, METHOD FOR CONTROLLING INDUCTIVE HEATING DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/069526
Kind Code:
A1
Abstract:
To control the output phase angle of resonant inverters in a mutual induction environment so as to keep the output phase angle within a predetermined range. An inductive heating device (100) provided with a plurality of resonant inverters (30a, 30b) for supplying power to each of a plurality of inductive heating coils (La, Lb) in a mutual induction environment, wherein the inductive heating device (100) is provided with a control circuit (40) for sharing the drive frequencies of the resonant inverters and controlling the drive frequencies is a shared manner so that the output phase angle of the plurality of resonant inverters is within a predetermined range. In addition, the coil current flowing through the inductive heating coils is individually controlled so that the phase angle is within a predetermined range.
