Polarized electric charge storage devices economically provide high
available capacitance. The present invention directly employs polarized
electrical charge storage (PECS) devices such as polarized capacitors or
electrochemical batteries in general AC applications with a novel circuit
topology. In one embodiment, an anti-series configuration of first and
second PECS devices are used within an AC network for enhancing operation
of the AC network. At least one DC source is provided for maintaining the
PECS devices forwardly biased while they are subjected to an AC signal.
The AC signal, which drives an AC load, is applied to the anti-series
devices. The devices are sufficiently biased by the at least one DC
voltage source so that they remain forwardly biased while coupling the AC
signal.
