First Claim
1. A polarized electric charge storage (“
- PECS”
) apparatus for operation in an AC network having an AC source and at least one load coupled to the AC source for receiving the AC signal, the PECS apparatus comprising;
at least first and second PECS devices in an anti-series configuration with one another, the anti-series PECS devices adapted to be operably connected to the AC network and subjected to the AC signal, and at least one DC source coupled to the first and second PECS devices for sufficiently forwardly DC biasing the devices to substantially prevent them from being detrimentally reverse biased by the AC signal.

Abstract
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.
