  • Electronic power-saving device
    Patent number: 8373311
    Abstract: A single-phase electronic power-saving device includes at least one power-saving unit. The power-saving unit includes two ceramic piece capacitors, a safe capacitor, an inductor, a SCR, a first resistor, a second resistor, a live wire and a zero line; the two ceramic piece capacitors connected in series as a whole is connected in parallel with the safe capacitor to two terminals of which are connected the anode and the cathode of SCR, respectively; the anode of SCR is also connected to one terminal of the inductor, the branch composed of the first and the second resistors connected in series is connected in parallel so that one terminal of which is connected to one terminal of the inductor and the other is connected to the cathode of SCR; the gate of SCR is connected between the first and the second resistors.
