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.
