Abstract

A new dual half bridge induction heating cooker circuit with multiple loads is proposed for reducing the acoustics noise which is caused by the difference between operating frequencies q adjacent loads. This circuit has minimum loss due to the zero voltage switching characteristic. According to the mode analysis of the proposed circuit, we explain the operation of the dual half bridge induction heating cooker circuit The proto-type circuit with 2.8kW power consumption is builted and tested to verify the operation q the proposed circuit.
