ABSTRACT:
A VAR generator is taught in which a thyristor controlled inductive element is used to provide lagging VAR's and a bank of parallel capacitors, each of which may be switched into and out of circuit cooperation independent of the other, is used to provide discrete levels of leading VAR's. The inductive element is utilized in conjunction with the discrete levels of leading VAR's to provide a continuum of VAR generation in the region between the discrete levels by providing continuously variable compensating or cancelling current for interaction with the discrete levels to provide an overall continuous range of VAR generation in the leading VAR region.
