Abstract
Power conditioning apparatus particularly suited for computer facilities and including non-linear input chokes connectible with line power. 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. Series tuned traps are coupled to the synthesizer network to avoid the development of harmonics above fundamental.
