Static power supplies, incorporating solid state switching devices, are rapidly becoming commonplace in the induction heating industry. Several different system approaches have been described in the literature (see Bibliography) from both the design and application viewpoint. The present paper covers a functionally similar system, but one which incorporates circuitry different from that previously described. This approach is intended for use in the 1 to 3 KHz range. At lower frequencies, the economics of other systems are more favorable whereas at higher frequencies currently available SCR switching speeds are inadequate.
