“…In the circuit-based simulation, we first derive an equivalent circuit model and then perform the transient numerical analysis. For these purposes, some circuit models of ESD generators have been proposed [4]- [6], [9]. Since the circuit models are composed only of elements which represent major effects during the discharging process, its computational cost is much lower than that of the full-wave simulation.…”

In this paper, we describe a hybrid circuit and electromagnetic simulation technique for electrostatic discharge (ESD) events. First, we perform the transient simulation of an equivalent circuit of an ESD generator. At the same time, a computational domain without the ESD generator is analyzed by means of the finite-difference time-domain (FDTD) method. The results from the SPICE-like and FDTD simulations are exchanged for each other by using analogy between the circuit theory and electromagnetics. The proposed method can reduce the computational cost significantly because we perform the FDTD simulation only for the reduced domain, which is much smaller than the whole domain. The adequacy of the proposed method is verified by comparing simulation results with measurement results.

“…However, it is necessary for the actual ESD simulation to include not only the circuit model of the generator, but also the proper models of other components in an immunity test, such as a target device under test (DUT) and a ground strap connected to the generator. In this situatoin, we have proposed a unified circuit modeling technique to compose the circuit model of the whole system [12]. In this technique, we derive the equivalent circuits of an ESD generator, ground strap, and target printed circuit board (PCB), and the equivalent circuit of the whole system is constructed by combining them with each other.…”

In this paper, we describe a framework for the accurate estimation of electrostatic discharge (ESD) events induced on realistic products. The framework is based on a unified circuit modeling and simulation technique to deal with the environment of an ESD immunity test including a device under test, a ground strap, and an ESD generator. First, the equivalent circuit model of the ESD generator used in a previous work is improved to achieve more accurate results from simulations. For this purpose, the circuit model is modified by adjusting the circuit parameters and inserting circuit elements. Then, we deal with the ESD events on a printed circuit board (PCB) with a chassis for the practical application of our framework. The PCB and chassis are modeled by using the multilayered finite difference method and excited by the modified circuit model of the generator. The adequacy of our approach is demonstrated by comparing the simulation results with measurement results.

This paper develops an improved non dominated sorting genetic algorithm II (NSGA-II) based on objective importance vector γ , abbreviated as γ-NSGA-II. Different importance levels for the multiple objectives are incorporated in the objective importance vector, which is applied to determine the individual selection of sorting individuals in the critical layer. And such an individual selection strategy is developed to the NSGA-II algorithm in order to obtain the optimized solution for a task which has multiple objectives with different importance. The differences between the γ-NSGA-II algorithm and the traditional NSGA-II algorithm are discussed in detail. A notch filter is designed for the conducted emission suppression of a transformer rectifier unit (TRU) used in C919 flight testing, and then the parameters optimization design of a notch filter is discussed and conducted based on the γ-NSGA-II algorithm. The non-linear relationship between the filter's parameters and the suppression effect of the conducted emission is also discussed with the help of an electromagnetic compatibility (EMC) evaluation model based on a back propagation (BP) neural network. The experimental results show that the optimized design of the notch filter is effective and the improved γ-NSGA-II algorithm be more specific. INDEX TERMS Suppression conducted emission, multi-objective optimization, NSGA-II, BP neural network, notch filter, autotransformer rectifier.
