Abstract The ion source is the key to NBI. It very sensitive overvoltage and overcurrent, breakdown frequently occurs between acceleration grid. core snubber most suitable surge suppression device achieve DC fault protection. This paper introduces some basic concepts, comparing snubber’s material properties important parameters. also concept of an equivalent circuit model for snubber, including...

It is an essential task of battery management system (BMS) to online estimate the State of Charge (SoC) of a Lithium-ion (Li-ion) battery, an important indicator of the remaining charge in the battery. Accurate modeling of the electrical behavior of a Li-ion battery can provide an accurate approximation of the battery dynamic characteristics during charging/discharging and relaxation phases. Th...

Lithium-ion battery State of Charge (SoC) estimation for Electric Vehicle (EV) applications must be robust and as accurate possible to maximize utilization ensure safe operation over a wide range operating conditions. SoC commonly utilizes filters such the Extended Kalman Filter (EKF) which rely on models, usually in form Equivalent Circuit Models (ECM). At low temperatures response current dra...

We present equivalent circuit models of skeletal muscle tissue for the directions parallel and transverse to the fiber. The parallel model is based on a distributed parameter equivalent circuit approach where the tissue between the electrodes is divided into small segments, each of which is represented by an equivalent circuit. Parameters for the equivalent circuits are calculated from the elec...

As the signal frequency increases, the accurate and fast modeling for vias structure in multi-layer substrate is very important to performance analysis of high speed circuit. According to the skin effect and RL ladder circuit model, the equivalent circuit of via base on structural segmentation is presented in this paper. Vias structure is decomposed into some segmented sub-structure based on th...
