Abstract: The number of years, not only electronic equipment, and its complexity, there has been substantial growth, which makes the system more vulnerable to modern types of electromagnetic interference. In order to solve the increasingly serious problem of electromagnetic compatibility of urgency, the ensuing electromagnetic compatibility testing situation has become more widespread and serious concern.

The main effect of the artificial mains network in which real-life [2]:

① provides input from the EUT port impedance looking into the entire network;

② will weaken the power supply voltage disturbances by setting the device, namely the setting device is coupled to the power supply from interfering with the test equipment;

③ reduce the effects of noise voltage of the external power supply networks.

The main task of this project is to design and produce a set of input impedance of 150 ohms artificial mains network. This paper introduces the basic meaning and basic principles of artificial mains network, second analysis of this topic artificial mains network 150 Ohm artificial network of internal components, including the fabrication and testing of the capacitor, resistor and inductor selection, and analysis Circuit design of the entire network; and a housing design artificial network; the third step of the subject of the design and production of artificial mains network circuit lap with experimental debugging. The fourth step is the design parameters of the artificial mains network (impedance and phase angle) conducted experiments to test and isolation, divided simulation pressure coefficients. The results show that the performance parameters of the subject of the design and production of artificial mains network in line with regulatory requirements.

Keywords: Artificial mains network, inductance coil production, performance parameters, debugging, simulation
