The invention relates to the field of circuit drive technology, in particular to a solenoid valve drive circuit. Including an input rectification filter circuit, a power supply circuit, and a control drive circuit; the input rectification filter circuit is electrically connected to the power supply, and the input rectification filter circuit outputs the filter voltage to the power supply circuit according to the power supply voltage; the power supply circuit outputs the supply voltage to the control drive circuit according to the filter voltage; The control drive circuit is electrically connected to the power supply circuit, and the control drive circuit includes a control chip. When the control chip receives the power supply voltage, the control chip outputs a wide pulse signal and a narrow pulse signal. In the prior art, although the solenoid valve can be effectively driven, the solenoid valve is easily burned due to the power consumption of the solenoid valve coil itself. Compared with the prior art, the present invention satisfies the requirement of exciting the solenoid valve by outputting a wide pulse signal, and satisfies the requirement of continuous operation of the solenoid valve through the narrow pulse signal, thereby effectively reducing the working current of the solenoid valve and further reducing the power consumption of the solenoid valve .
Description
technical field [0001] The invention relates to the technical field of drive circuits, in particular to a solenoid valve drive circuit. Background technique [0002] With the continuous development of technology, solenoid valves are widely used in different equipment, so how to effectively drive the solenoid valve to work becomes very important. Although the existing technology can effectively drive the solenoid valve, during the use of the solenoid valve, due to the influence of the driving circuit and the characteristics of the solenoid valve coil itself, the solenoid valve coil is prone to burning damage as the use time increases. It can be seen that it is very necessary to design a driving circuit that can make the operation of the solenoid valve coil more stable. Contents of the invention [0003] Aiming at the technical problems of the prior art, the present invention provides a solenoid valve driving circuit. [0004] In order to solve the problems of the technolo...
