Patent ID: 8373311

Claim:
An electronic power-saving device, comprising at least one power-saving unit which comprises: two ceramic capacitors electrically connected in series; a safety capacitor electrically connected to said two ceramic capacitors in parallel; a silicon controlled rectifier having an anode, an cathode, and a gate, wherein said anode and said cathode are electrically connected to two terminals of said safety capacitor respectively; an inductor electrically connected between said safety capacitor and said silicon controlled rectifier; and a first resistor having one terminal electrically connected to said anode of said silicon controlled rectifier; a second resistor having one terminal electrically connected to said cathode of said silicon controlled rectifier, wherein another terminal of said first and said second resistor are electrically connected with each other in series, wherein said gate of said silicon controlled rectifier is electrically connected to a junction of said first resistor and said second resistor; a third resistor having one terminal electrically connected to said first resistor; an indicator having one terminal electrically connected to another terminal of said third resistor in series, and another terminal electrically connected to a junction of said second resistor and said safety capacitor; and a ground wire arrangement made of metal.
