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 paral lel circuit to protect electrical and electronic equipment from transients from an electrica l 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 p ole being fed by said first uni-directional diodes; (c) uni-directional diodes attached an d feeding back to line, neutral and/or ground connection, and being fed from a negative pole of the DC capacitor; and (d) a discharge resistor in parallel with said DC capacitor.
