   Generation System for Series Hybrid Powertrain Based on the Dual Two-Level Inverter

Abstract: A multilevel converter in the â€˜dual two-levelâ€™ configuration is proposed as the core of a hybrid series powertrain. The generation system of the powertrain is constituted by an internal combustion engine (ICE) connected to a three-phase permanent magnet synchronous generator (PMSG). This machine is in the three phase open end winding configuration and is driven by the dual two-level inverter. The two dc-links of the multilevel converter supply two motor drives connected to the wheels. The control algorithm of the generation system is combined with a proper modulation strategy of the dual two-level converter allowing to share the generated power between the two output drives at each switching period. The power sharing capability of the generation system satisfies the different power demand from the two output drives. This architecture can be applied to road vehicles (i.e. buses, urban light truck) where the two wheels are driven by the two motor drives. This powertrain configuration could be easily integrated with a battery energy storage system for pure electric operation of the system.

   High-Voltage Bi-Directional DC-DC-Converter for Advanced Electric Locomotives

Abstract: Existing DC current high power locomotives at standard input voltages of 3 kV, 1.5 kV, or 0.75 kV can be connected to high-voltage catenaries operated at n - times the DC voltage level via a novel n cell capacitor switching converter. Each cell voltage is defined by the locomotive power train DC input level, thus balancing of capacitor voltages is not required.

Abstract: The aim of this paper is to give an overview of the semiconductor solutions for the micro-hybrid automotive systems as based on the technologies existing today. First, the motivation for the micro-hybrid, especially for the belt driven starter alternator, is given, followed by the system overview. Alternator in question is the Lundell type alternator with 3-phase and 6-phase configuration. Both starting of the engine and the high efficiency alternator mode are considered. The application requirements are discussed and mapped directly into semiconductor requirements. Special attention is given to power MOSFETs and the driver circuit performance as components of choice for low voltage automotive networks. System demonstrator based on both 3-phase and 6-phase alternator is presented, together with experimental results. Next point is the investigation of packaging and interconnection options, with quality and reliability of power modules. In the end, a future outlook is given.
