A new prototype of a soft-switching three-phase utility frequency ac to single-phase high-frequency ac direct power converter for induction heating (IH) applications is presented in this paper. The newly-proposed ac-ac converter features direct frequency conversion under the principle of series resonance and soft switching operations with minimized number of bidirectional switches. The validity of the proposed ac-ac converter is revealed by essential experimental results with a 3.5 kW-40 kHz prototype.
