A laboratory setup is developed to experimentally reinforce the student’s understanding of multilevel neutral point clamped inverter operated with various multicarrier and modulation reference signals. Sixteen combinations of carrier and reference signals out of many more possible are studied in this setup. The lab module is project-based and is designed to perform experiments for the ‘advanced power electronics and drives’ course at the undergraduate level. The hardware implementation details of the multilevel inverter are given in detail for reference to the teachers, students and researchers. Flexible hardware able to be driven by an analogue pulse-generation circuit is explained here or by an external digital programmable device is developed. With the help of dSPACE, complex reference signals are produced for performance analysis.

开发了实验室设置，以通过实验增强学生对采用各种多载波和调制参考信号运行的多级中性点钳位逆变器的理解。在此设置中，将研究16种载波信号和参考信号的组合，其中包括更多种可能的信号。实验室模块是基于项目的，旨在在本科层次上为“高级电力电子和驱动”课程进行实验。详细介绍了多电平逆变器的硬件实现细节，以供教师，学生和研究人员参考。在此说明了可以由模拟脉冲发生电路驱动的柔性硬件，或者开发了外部数字可编程设备。借助dSPACE，可以产生复杂的参考信号以进行性能分析。
