Abstract

Applying co-simulation technology is a very important trend in power electronics simulation, which can make full use of the merits of different software to improve the efficiency of building up a system. In this paper, a simulation platform for three-level adjustable speed drive (ASD) based on co-simulation of PSIM and SIMULINK is presented, which includes the interface between PSIM and SIMULINK, main circuit in PSIM, space vector pulse width modulation (SVPWM), dead time and minimum pulse width, view of output voltage and its Fourier analysis in SIMULINK. Based on this platform, the cause of large current when motor starts is studied. Simulation and experimental results show that the minimum pulse width contributes a lot for the large starting current of the ASD. In conclusion, applying the simulation platform introduced in this paper, the dynamic behavior of the three-level ASD can be easily studied, which reduces the cost and improves efficiency at the same time compared to hardware investments, and may help to realize the optimal design of the ASD in practice

三级调速驱动系统的PSIM和SIMULINK联合仿真

联合仿真技术的应用是电力电子仿真的一个重要趋势，它可以充分利用不同软件的优点，提高系统的构建效率。提出了一个基于PSIM和SIMULINK联合仿真的三电平调速驱动器(ASD)仿真平台，包括PSIM和SIMULINK的接口、PSIM主电路、空间矢量脉宽调制(SVPWM)、死区时间和最小脉宽、输出电压视图及其在SIMULINK中的傅里叶分析。在此基础上，研究了电动机起动时产生大电流的原因。仿真和实验结果表明，最小脉冲宽度对ASD的大启动电流有很大的贡献。综上所述，利用本文引入的仿真平台，可以方便地研究三级ASD的动态行为，与硬件投资相比，降低了成本，同时提高了效率，有助于在实践中实现ASD的优化设计
