| description | The utility model relates to an energy-saving and life-prolonging AC voltage regulator, which is a regulator for regulating the AC voltages of household appliances. The utility model is characterized in that control poles of an ordinary thyristor are connected in series to a switch circuit which is composed of a transistor, a crystal diode, a capacitor and a resistor and a compensating circuit to expand the phase shift range and keep the phase shift angle stable. The influence on mass production brought about by the dispersancy of the parameters of the control poles of the thyristor can be overcome through regulating two resistors which are connected in parallel with a potentiometer and the thyristor. The phase shift angle at the initial position after the utility model is switched on is more than 150 DEG by changing the connection method of the potentiometer with a switch, and the starting current can be limited to obtain the purpose of prolonging the service life of the utility model. The utility model has the advantages of long service life and low cost; the utility model is with a socket, and is suitable for matching with various household appliances such as electric fans, etc. |
