Abstract Although the superior performance of SiC MOSFET devices has beenvalidated by many studies, it is necessary to overcome many technical bottlenecks to make SiC MOSFET gradually replace Si-based power devices into the mainstream. In view of the current situation where the performance of SiC MOSFETs in power conversion devices cannot be evaluated well at this stage, it is necessary to carry out fine modeling of SiC MOSFETs and establish accurate simulation models. In this paper, the powerful mathematical processing capability and rich modules of Matlab/Simulink are used to build a SiC MOSFET model, and then the product data sheet is compared with the fitted data. The results show that the switching simulation waveforms are in general agreement with the data sheet waveforms, and the error is less than 7%. Verifing the accuracy of the model and reducing the difficulty of modeling, it provides a new idea for establishing the circuit simulation model of SiC MOSFET in Matlab/Simulink.

In view of the demand of circuit fault simulation analysis, a novel circuit simulator for fault simulation was designed to overcome the shortcomings of traditional circuit simulation tools in fault simulation. The principles and method of this simulator were proposed, which focus on the realization of the basic functions and weakens detail characteristics. Based on the method, the components simulation models and fault models with the combination of the numerical variable with logical variable were built. Moreover, the implementation algorithm and simulation flow were introduced to show how to simulate a circuit based on this simulation model. At last, an example was simulated to verify the feasibility of this method. It is shown that, this circuit simulator will become a valuable tool for the circuit fault simulation and analysis.

In this article, taking a specific underwater hydraulic system as the research object, a closed loop circuit and a closed non-loop circuit simulation models are established; and through a single factor analysis, the interior factors such as different pipeline damping settings, underwater accumulators and actuators, and external factors such as water depth and return distance are analyzed. System response curves of these factors are obtained. Based on the single-factor simulation data, the partial correlation theory is used to analyze the correlation of the influencing factors of the control response for the underwater hydraulic system, and the order of the main factors affecting the control response of the underwater hydraulic system is obtained, which provides a reference for improving the response of the underwater hydraulic system.

Behavior models are proposed for HSPICE simulation of first-, second- and third-generation current conveyors. They can be used to speed up the exploration and verification of current conveyor-based circuit designs. To demonstrate the feasibility and workability of the proposed HSPICE simulation models, they are used as the current measuring devices for grounded and floating current sensing, and the simulation results are consistent with the theoretical expectation. The flexibility in the current sensing capability of the CCIII is also shown by a practical example using the behavior model. HSPICE simulation results are given.
