Abstract

1,009,522. Systems for supplying induction heating apparatus. A. TAGLIAFERRI. April 24, 1962 [April 25, 1961], No. 15482/62. Heading H2H. An electric system for controlling the useful power fed to an apparatus such as an induction heating furnace comprises a pair of input terminals supplied with alternating current with a reactance Yz, which may be either capacitive or inductive, connected across the input terminals, a capacitive potential divider comprising at least two capacitors Ys and Yp, Yp<SP>1</SP> connected in parallel with the reactance Yz, the apparatus Ro being connected across part of the potential divider Yp, Yp<SP>1</SP>, the system being cnaracterized in that all the reactive elements are variable in order to control the load voltage and the system power factor. The Specification includes a theoretical discussion on the operational characteristics of the system.
