SYSTEM FOR ESTIMATING LOAD IMPEDANCE OF INDUCTION HEATING APPARATUS

摘要

PURPOSE: A load forecasting system for an induction heating apparatus is provided to prevent facilities from malfunctioning or excess currents from occurring by sensing the sudden changes of the load and grapping the properties of a metal board in advance. CONSTITUTION: A measuring part measures the properties of voltage or current in an induction heating apparatus. The measuring part measures the input voltage in the induction heating apparatus and voltage at the both ends of the capacitor(130). The load forecasting part(180) predicts the impedance of an object or the heating coil(150) by using the measured properties of voltage or current. The load forecasting part predicts the impedance of the heating coil or the object by using an adaptation forecasting algorithm.
