Latest Developments in Static High Frequency Power Sources for Induction Heating

This paper describes the basic principles of operation and control of three closely related types of static thyristor inverter circuit, which have been developed specifically for induction heating applications. The circuits described constitute a complete and compatible line of static frequency converters, capable of meeting the needs of virtually all practical induction heating applications, requiring frequencies from 180 Hz up to 10 kHz, at power levels from 100 kW upwards.
