Emitter Turn-off (ETO) thyristor is one of the present state-of-the-art high power semiconductor devices. The newest version of ETO (Gen-4 ETO) is more intelligent and reliable. Packed with advanced features as well as superior performance, ETO device and ETO-based power converters are very attractive for large electric drives. This paper presents the ETO Light neutral-point-clamped (NPC) converter design and thermal analysis. The modular digital controller architecture for this converter is proposed in order to improve the system reliability and increase its expansion flexibility. As a solution to further increase the converter output power, the ETO Light active NPC (ANPC) converter is presented, and moreover its fault tolerant capability is discussed.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132772267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a fuzzy logic based power management strategy considering a regenerative braking control of the electric motor is presented for proton exchange membrane (PEM) fuel cell and Nickel-Metal Hydride (Ni-MH) battery hybrid vehicular power system.

Hybrid power systems combine multiple complementary power generation and energy storage technologies to achieve a level of system performance that is not possible for those involving a single technology. Complicated dynamic interactions of the hybrid power system elements, coupled with stringent safety, power quality and efficiency requirements, impose challenging coordinating control and dynamic optimization problems. To facilitate optimization and power management strategy development for system level design, an experimental testbed was developed at the University of Michigan by the authors. A large signal dynamic model of the DC hybrid power system testbed is developed and validated by experimental results.

Based on the analysis of the system architecture, the dynamic model of the air system is developed, in which a semi-empirical model of blower is built and the impact of parasitic power of the blower on the net power of the fuel cell system is taken into consideration. The accuracy of the model is verified by comparing the simulation results with the experimental data. Then the reason for instability is studied using both model simulation and theoretical analysis which employs the automatic control theory based on the linearized system model. The analysis result shows that the feedback loop of the blower current is the cause for instability. Furthermore, a new control algorithm is designed. The new control algorithm opens the current loop and adapts the optimized control parameters. The test results show that the air mass flow rate is stable and the improved system has a good performance.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128080568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
