Abstract :
In this paper, the main steady-state frequency properties of the LLC circuit are described. The advantage of its use on induction heating applications is proved, in contrast with the SRI (series resonant inverter). This analysis will allow the future design of a frequency control strategy for the inverter. Finally, a simple design algorithm is proposed, which satisfies the power specifications and limits the stress current in the switches
