Experimental investigation of full bridge series resonant inverters for induction-heating cooking appliances

In this paper, a full-bridge resonant-type IGBT inverter suitable for heating magnetic and nonmagnetic materials at high frequency is experimentally described. A series arrangement of capacitors is adopted and an optimum mode of operation is proposed. The actual performance was tested on an experimental prototype of full bridge series resonance inverter for induction-heating cooking appliances. The low-cost developed hybrid inverter is characterized by simplicity of design and operation. Some analysis and detailed experimental results are presented.
