High efficiency DC-AC converters suitable for high frequency induction process heating applications

An outline is given of recent work on solid-state units suitable for high-frequency induction heating applications. High-efficiency, high-frequency units suitable for application in the 1 to 10 MHz range have been successfully constructed and tested using standard power MOSFET packages. Power levels in excess of 150 W at 7 MHz and 500 W at 3.3 MHz with conversion efficiencies of over 90% have been achieved.<<ETX>>
