METHOD OF CROSSTALK REDUCTION FOR MULTI-ZONE INDUCTION HEATING SYSTEMS

摘要

Reduction of crosstalk between induction heating coils in an induction heating apparatus and particularly to reduction of crosstalk in a multi-zone induction heating system provides greater reliability for the power modules It comprises the steps of monitoring currents in plurality of induction coils in which a frequency of the current in each of the induction coils is similar, detecting in each current a distortion developed by a phase difference of the current in an adjacent one of the induction coils, and shifting a phase of the current in one of the induction coils in which the distortion is detected until the distortion is eliminated.
