Patent ID: 8138633

Claim:
An electronic power-saving device, comprising two power-saving units electrically coupled with each other, wherein each of said power-saving units comprises: two ceramic capacitors being electrically connected in series; a safety capacitor electrically connected to said two ceramic capacitors in parallel; an inductor; a silicon controlled rectifier (SCR), wherein two terminals of said safety capacitor are electrically connected with an anode and a cathode of said SCR respectively, wherein said anode of said SCR is electrically connected to one terminal of said inductor; and first and second resistors electrically connected in series, wherein said first and second resistors are electrically connected with said anode and said cathode of said SCR respectively, wherein the gate of said SCR is electrically connected with the junction of said first and second resistors; wherein one of said power-saving units is a strong power-saving unit while another said power-saving unit is a weak power-saving unit, wherein the charge of said ceramic capacitors, said safety capacitor, said inductor, and said SCR of said strong power-saving unit is larger than the charge of said ceramic capacitors, said safety capacitor, said inductor, and said SCR of said weak power-saving unit.
