Enclosure circulation of Gas Insulated Switchgear (GIS) and Very Fast Transient Overvoltage (VFTO) are harmful to many respects of power system, including system's security, stability and economic. The effective inhibition of GIS enclosure circulation and VFTO has attracted wide attention. In this paper, GIS enclosure circulation and transient ground potential has been modeled and analyzed. Firstly,...
In this paper, a very fast capacitor assignment algorithm capable of finding an optimized decoupling solution scheme that meets a predefined target impedance for a given power distribution network (PDN) is presented. The algorithm provides an optimal combination of decap values and decap locations while minimizing the number of decoupling components needed to meet RL-type target impedances. The algorithm...
In this paper, the issues of derating design of integrated circuit are discussed. The disadvantage of the traditional derating design method is discussed. This paper puts forward the method using Saber to simulate the electric stress of the electronic product, which can improve the accuracy of the result and the speed of the transient stress calculation. The method that uses derating analysis based...
Failure mode and effects analysis (FMEA) is widely used in the product design process of various fields, and is of great significance for the product reliability, testability and safety. Aimed at the problems of FMEA existing in the electronic product design and manufacturing process, this paper proposed to carry out FMEA work based EDA simulation, through the establishment of electronic design automation...
The Co-simulation of Saber and Simulink is raised in the automotive electronic throttle control system reliability analysis aiming to model sharing of different simulation software. The principle of co-simulation, general process and the method of parameter setting are introduced based on Saber and Simulink. The co-simulation of electronic throttle control system describes process realization of co-simulation,...
Electromagnetic interference (EMI) is becoming more serious when the data rate of the digital system continues increasing. However, its modeling and analysis are very challenging. In this paper, a novel electromagnetic superposition method is developed to model the IC packaging electromagnetic emission. It employs the equivalence principle to obtain the electromagnetic field response over a broad...
The sensor is a multi-board system composed of backboard and other plugging boards. It is a crucial problem that how to assure the signal integrity (SI) for such a complex system. In this paper, we mainly discuss the various signal integrity plots of critical signals in digital circuit board and EMC problems in the multi-board sensor system. The SI and EMC conditions can be improved with the help...
In printed circuit board (PCB) designs, it is common to split power/ground planes into different partitions, which leads to more crosstalk among signal traces that route crossing a split. It is of general interest to develop a crosstalk model for various geometric parameters. However, the long time required to simulate the structure with any given set of geometric parameters renders general modelling...
This paper presents the behavioral quantification analytical method of electromagnetic susceptibility (EMS) for electronic devices at board level. A full-wave electromagnetic modeling technique coupled with a circuit-based method is used in this paper to quantitatively describe the interference immunity of sensitive components in the circuit board. The behavioral model for quantitative analysis of...
Solar energy is considered as one of the most effective, less expensive, harmless and less environment pollution effect of renewable energy sources, the problem of using solar power including varying weather condition brings different output power of the photovoltaic (PV) array, which may cause a serious waste of solar power, for solving this problem, a Maximum Power Point Tracking (MPPT) strategy...
