Abstract :
A new high-performance high-frequency (HF) soft switching inverter for induction heating (IH) applications is presented in this paper. By adjusting a phase difference angle between the two resonant currents based on the phase shift-control scheme, the IH load resonant current can be regulated continuously and flexibly under the full-load range soft switching conditions. The performances on the output power control and the soft switching operations are demonstrated in experiments using a 450W-70 kHz prototype, then its topological validity is evaluated from the practical point of view.
