Abstract

The use of a NPC-type multilevel converter as multiport inverter (MPI) has recently been considered a promising solution for the compact integration of multisource systems in various applications. This paper presents a broad analysis of a quasisingle stage propulsion system (QSS) that employs an NPC-type MPI and a downsized boost dc-dc converter for an urban tram vehicle with overhead line connection and onboard batteries. The control and dynamic performance are detailed and validated experimentally. Furthermore, the power losses, VA rating, weight, volume, and reliability of the QSS system are evaluated and benchmarked against a conventional architecture for a case-study catenary/battery tram model. The analysis reveals that the QSS system can achieve significant savings in volume, weight, and round-trip energy efficiency, higher reliability due to intrinsic redundancy, but with increased VA rating, part count, and complexity.
