Closed Loop Controlled AC-AC Converter for Induction Heating

Authors: ,


A single-switch parallel resonant converter for induction heating is simulated and implemented. The circuit consists of input LC-filter, bridge rectifier and one controlled power switch. The switch operates in soft commutation mode and serves as a high frequency generator. Output power is controlled via switching frequency. Steady state analysis of the converter operation is presented. A closed loop circuit model for AC to AC converted induction heating system is also proposed. Experimental results are compared with simulation results.
