The energy-saving unit is a four-port network and consists of a first input port N1, a second input port N2, a first output port T1, a second output port T2, a transient voltage suppression diode TVS, an AC-DC conversion circuit 101, a control pulse generation circuit 102, and a pulse control special-shaped bridge circuit 103.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to an "electricity-saving unit for an AC solenoid valve or an AC contactor" with an electricity-saving function. Background technique [0002] AC solenoid valve (AC solenoid valve) is a type of solenoid valve, and it is a low-voltage electrical appliance widely used in household appliances and industrial control equipment. Its characteristic is to connect AC voltage at its input end, and use the electromagnetic force generated by the excitation coil to drive the valve to open or close. [0003] The AC solenoid valve is mainly composed of an excitation coil, a valve core and a return spring. Figure 1a , Figure 1b It is a schematic diagram of controlling fluid (gas or liquid) on and off for AC solenoid valve; Figure 2a , Figure 2b It is a schematic diagram of the AC hydraulic solenoid valve used in hydraulic equipment to control the flow of "hydraulic oil".
