Abstract :
A new version of an AC-AC converter circuit for induction heating has been presented and analyzed. The basic features of the proposed circuit are as follows: the converter input current is practically sinusoidal and its power factor is close to unity; the output current does not include DC-component and thus it prevents additional losses and eliminates the possibility of the installation of the separating transformer; the circuit topology is very simple and includes only one power switch, which operates in a soft commutation regime; and the converter provides a wide range power control (0.3-1). The computer simulation and the experimental results demonstrate the actual capability and successful performance of the proposed converter.
