摘要

介绍了一种基于spice的宽带隙(WBG)器件电压源逆变器(VSI)和电流源逆变器(CSI)评估平台。VSI拓扑结构几十年来一直主导着电机驱动系统。在以前的研究中已经确定了在vsi中插入更换WBG开关所引起的重大问题。作为一种替代解决方案，CSI与基于wbg的快速切换设备具有更好的兼容性。本文选择氮化镓(GaN)作为未来电力电子领域最有前途的候选材料之一进行评价。基于定制的VSI和CSI DPT，对VSI和CSI开关的开关损耗进行了估计。此外，还比较了基于gan的CSI和VSI的系统效率。利用LTspice作为评估/仿真平台，考察了VSI和CSI在高频工作下的性能。

Performance Evaluation of WBG-based Devices in VSIs and CSIs

This paper introduces a SPICE-based evaluation platform for wide band-gap (WBG) devices based voltage source inverter (VSI) and current source inverter (CSI). VSI topology has dominated motor drive system for decades. Significant problems caused by drop-in replacement of WBG switches in VSIs were identified in previous studies. As an alternative solution, CSI shows greater compatibility with fast-switching WBG-based devices. Gallium Nitride (GaN) as one of most promising candidate in future power electronics field is selected for evaluation purpose in this work. Estimation of switching loss of VSI and CSI switches have been made based on tailored VSI and CSI DPT. In addition, the system efficiency comparison between GaN-based CSI and VSI is addressed. The LTspice is used as evaluation/simulation platform to examine the performance of VSI and CSI under high-frequency operation.
