Abstract

The invention discloses an electrical system based on linear driving. The electrical system based on linear driving is mainly composed of a front-end processing circuit, an amplification circuit connected with the output end of the front-end processing circuit, a pulse rectifying circuit connected with the output end of the amplification circuit, a fine adjustment circuit connected with the pulse rectifying circuit and a warning circuit connected with the output end of the pulse rectifying circuit. The electrical system based on linear driving is characterized in that a linear driving circuit is arranged between the amplification circuit and the pulse rectifying circuit and is composed of a driving chip U, a triode VT2, a triode VT3, a triode VT4, a triode VT5, a polar capacitor C7 and the like, the positive electrode of the polar capacitor C7 is connected with the amplification circuit, and the negative electrode of the polar capacitor C7 passes through a resistor R16 and then is connected with an IN1 pin of the driving chip U. According to the electrical system based on linear driving, due to the fact that the linear driving circuit is arranged, the electrical system can be more stable.

Description

Technical field [0001] The invention relates to an electrical system, in particular to an electrical system based on surge current limitation. Background technique [0002] As people's requirements for the quality of life increase, electrical is one of the core disciplines in the modern science and technology field, and it is also an indispensable key discipline in today's high-tech fields. It is the tremendous progress of electronic technology that has promoted the arrival of the information age based on computer networks and will change the mode of human life and work. The current electrical system cannot detect whether the system voltage is normal. If the system voltage or current is too high or too low, it will affect the normal use of the terminal electrical load. This not only affects the service life of electrical loads, but also seriously affects people's production and life. Summary of the invention [0003] The purpose of the present invention is to solve the defect th...
