Abstract. Light emitting diode( LED) is widely used because of its high efficiency, environmental protection, long life and so on. However, the use of LED is affected by the performance of the driving power supply, especially in the complex and poor working environment. Therefore, it is very important to improve the stability of the driving power supply, and to add the lightning protection circuit to the LED driver technology. According to the basic requirements of multilevel surge protection, this paper analyses the lightning protection circuit of a common LED driving power supply. IntroductionWith the rapid development of LED technology, LED has been widely used because of its high efficiency, long life and environmental protection and so on [1][2][3]. The use of LED also needs to match the corresponding drive power. However, the life of the drive power supply is much less than the life of the LED light source, which severely restricts the overall life of LED lamps. In addition, LED drive power supply environment is sometimes relatively poor, especially in the natural environment of lightning [4].At present, the protection circuit almost will be put in the input of the LED driver power supply.The components that used to ensure the safe and stable operation of the circuit have more types, which including gas discharge tube, a voltage sensitive resistor, diode and positive temperature coefficient thermistor (PTC), but the precise research on lightning protection circuit model is still few. People just based on a single or a few parameters to design the circuit, failing to consider the overall performance of the circuit, insufficient element short life, lightning residual pressure is too large [5][6].To solve the above problems, this paper puts forward to optimize the lightning protection circuit, the circuit model is built by simulation software to verify the design, to provide a more comprehensive reference to the power supply protection circuit, according to the basic requirements of multi-level protection surge, lightning protection circuit principle analysis of a common LED driver and the existing problems.

“…The Mardir-Saha model [6] is also derived from the IEEE model, but with a modified internal structure. On the other hand, original models such as the Tominaga model [7], Kim model [8], Popov model [9] or others seem also promising for various applications. Individual models, internal structures, and their comparison in simulations of the lightning strokes in EMTP/ATP are further presented by the authors in [5], [10]- [15].…”

-This paper describes the possibilities for mathematical modelling of gap-less surge arresters in the simulation software DYNAST. This tool does not belong to standard modelling softwares in the field of electric power engineering. However, it may provide some key advantages when compared to more frequently used software such as EMTP-ATP and MATLAB-Simulink. Description of the metal oxide varistor modelling at temporary and switching overvoltages, fast-front states, and lightning strokes is presented. More information about the defined internal structure of the surge arrester models and ways for implementing respective V-I characteristics are provided. To verify the correct behaviour of the models, both slow and fast overvoltage scenarios are simulated and evaluated. Keywords -metal oxide varistor (MOV), gap-less surge arrester, surge arrester model, V-I characteristic of the surge arrester, temporary and switching overvoltages, lightning stroke, simulation software DYNAST

“…When a MOA is subjected to an electric system operating voltage, its resistance is high enough that the leakage resistive current can be neglected. However, due to the highly non-linear voltage-current (V-I) characteristics, when the MOA is subjected to temporary overvoltages or transient surges, the equivalent resistance become much smaller, and the resistive dynamic behavior is predominant [3][4][5][6]. Due to these non-linear V-I characteristics and excellent current/energy absorption capabilities, MOAs are widely used in the electrical power systems [1][2][3][4][5][6].…”

Metal-oxide arresters (MOAs) are used to absorb the electrical energy resulting from overvoltages in power systems. However, temperature rises caused by the absorbed energy can lead to the electrothermal failure of MOAs. Therefore, it is necessary to analyze the electric and thermal characteristics of MOAs. In this paper, in order to study the electric and thermal characteristics of MOAs under power frequency voltage, an improved electrothermal model of an MOA is presented. The proposed electrothermal model can be divided into an electric model and a thermal model. In the electric model, based on the conventional MOA electric circuit, the effect of temperature on the voltage-current (V-I) characteristics of an MOA has been obtained. Using temperature and applied voltage as input data, the current flows through the MOA can be calculated using the artificial neural network (ANN) method. In the thermal model, the thermal circuit of a MOA has been built. The varistor power loss obtained from the electric model is used as input data, and the temperature of the zinc oxide varistors can be calculated. Therefore, compared with the existing MOA models, the interaction of leakage current and temperature can be considered in the proposed model. Finally, experimental validations have been done, and the electrothermal characteristics of an MOA have been studied by simulation and experimental methods. The electrothermal model proposed in this paper can assist with the prediction of the electric and thermal characteristics of MOAs.
