STROMQUELLE UND VERFAHREN ZUM INDUKTIONSERWÄRMEN VON GEGENSTANDEN

摘要

A power source for induction heating of articles containing ferromagnetic particles. An arrangement including the article is exposed to an electromagnetic field at a first power level for a first predetermined period of time and, subsequently to an electromagnetic field at a second power level for a second predetermined period of time. In comparison to conventional power sources, the article may be exposed to an electromagnetic field for a longer period of time without damage.
