Abstract
Power conditioning apparatus particularly suited for computer facilities and including non-linear input chokes connectable with line power. These chokes are structured having a center leg configured to define a varying gap having a narrowest flux transfer region located centrally with respect to a surrounding shell structure. The gap configuration expands uniformly outwardly from this narrowest region. The outputs of the input chokes are serially, magnetically coupled through primary windings to pulse saturable reactors of a synthesizing network which includes a capacitor bank and operates to synthesize a sinewave output. The capacitance values of the capacitor bank are selectively distributed between the primary, isolation windings and the pulse saturable secondary or regulator components of the synthesizer network to achieve important improvements in system efficiency.
