Series resonant multi-inverter prototype for domestic induction heating

The series resonant multi-inverter topology has proved to be effective versatile and cost-effective solution to implement multi-coil induction heating cookers. A high power density prototype, which can supply nine induction loads, has been designed to check the last progress and researches in this field. In order to measure the main parameters of the converter, the prototype has a monitoring system. A communication system allows getting the measurements and to change the modulation and control strategies from PC. In addition, the developed prototype has made possible the fast development of some application examples such as pot detection and power control.
