ABSTRACT:
The invention is a combination of an altered AC to DC circuit utilized with typical power protection components for improved power protection purposes. More particularly, in accordance with the present invention there is provided a parallel circuit to protect electrical and electronic equipment from transients from an electrical system. The circuit comprises (a) first uni-directional diodes attached to line, neutral and/or ground connection of the electrical system; (b) a DC capacitor with a positive pole being fed by said first uni-directional diodes; (c) uni-directional diodes attached and feeding back to line, neutral and/or ground connection, said negative pole feeding said second uni-directional diodes; and (d) a discharge resistor in parallel with said DC capacitor.
