This paper presents a new single-stage utility frequency ac-high frequency ac resonant power converter for high frequency induction heating applications.The newly-proposed ac-ac converter features a boost converter and full bridge resonant inverter integrated circuit with a source voltage sensorless control system.The experimental results of a 3.0kW-40kHz prototype are demonstrated on zero voltage soft switching(ZVS) operations and steady-state character-istics,then the validity of the proposed ac-ac converter is revealed from a practical point of view.
