Abstract

An induction heating appliance has magnetically active parts on the top and is otherwise completely encapsulated in an electrically insulating and heat conductive material. The electrical connection is by means of a plug. A number of such appliances may be supplied with power in the range 20 kHz-100 kHz via coaxial cables leading to a central power supply converter. The unit is intrinsically safe and can be either installed or free standing.
