Abstract
Rolling stock manufacturers are developing a new generation of multimode rail vehicles equipped with a combination of hydrogen fuel cells and energy storage devices. Multimode trains benefit from high energy efficiency, lower current absorption and voltage fluctuations on the main supply, and low or null local emissions when running without electrification. Laying at the core of multimode traction architectures, power electronic converters interconnect and control the energy flows among power sources, storage devices, and traction loads. To cope with the low specific energy and power of the onboard sources and storage devices, compact and lightweight power electronics are required. This Ph.D. thesis aims at exploring the integration and control of the NPC Multi-Source Inverter (MSI) as main traction converter of multimode rail vehicles to reduce the size and weight of the onboard traction equipment. By providing a direct connection between two dc sources and one ac load in a single conversion stage, the MSI can reduce the power rating and size of the onboard dc/dc converters. A broad review of the traction architecture and energy control of recent multimode vehicles is first presented. The concept and fundamentals of the MSI are then revised, and an original PWM strategy for the converter is presented, which overcomes all the limits of the established literature approach and increases the feasible operating modes of the MSI. The integration and coordinated control of the MSI and dc/dc converter in a semi-active traction architecture are then discussed and validated experimentally. Finally, numerical investigations are carried out to quantify the effective reductions in size and weight achieved by an MSI-based traction architecture for two case studies based on real multimode vehicles.
