Abstract
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.
