GOALI: Novel Integration of AC/DC Charger and DC/DC Converter for Plug-in Hybrid Electric Vehicles

本研究旨在开发一种适用于插电式混合动力汽车(PHEV)的20kW新型集成双向变流器。该集成转换器具有更少的组件，并且更小且更具成本效益。该方法是将AC/DC整流器和双向DC/DC转换器集成在一个拓扑中用于混合动力电动汽车。由于其高度的复杂性和高度的研究导向性，该行业在任何PHEV转换套件中都没有解决这个问题。然而，对国家来说，重大的环境和经济利益使其成为NSF支持的合适的及时项目。该项目的智能优势在于集成双向转换器的设计、优化和开发，通过插座和再生制动为安装在车辆上的电池充电，从而提供更高的燃油经济性。更广泛的影响是确保最高质量的教育、研究和工程一体化，以满足国家汽车行业新兴的劳动力和需求。该项目团队将教育作为该项目的一个组成部分加以推广。女性和少数族裔研究生将参与拟议的项目。PI计划在他的教学课堂(欧洲经委会764--车辆动力系统)中使用调查结果。该项目将通过开发更清洁、更高效的汽车以及培训工程师开发更高燃油经济性和更低排放的汽车来造福社会。考虑到北美每年生产的汽车超过1500万辆，这对社会和环境具有重要意义。

The objective of this research is to develop a 20kW novel integrated bi-directional converter for plug-in hybrid electric vehicles (PHEVs). The integrated converter has fewer components and is smaller and more cost effective. The approach is to integrate the AC/DC rectifier and bi-directional DC/DC converter in one topology for PHEVs. This issue has not been tackled in any PHEV conversion kit by the industry because of its high level of complication and highly research-oriented nature. However, major environmental and economical benefits for the nation make it a suitable timely project for the NSF support. The intellectual merit of this project is in the design, optimization, and development of the integrated bi-directional converter to provide much higher fuel economy via charging the battery installed on the vehicle through outlet and regenerative braking. The broader impact is ensuring highest quality integrated education, research, and engineering to meet the emerging workforce and needs of the nation's automotive industry. The project team promotes education as an integrated part of this project. Female and minority graduate students will participate in the proposed project. The PI plans to use the results of the investigations in his teaching classroom (ECE 764-Vehicular Power Systems). The project will benefit society by developing cleaner and more efficient vehicles and by training engineers to develop automobiles with higher fuel economy and lower emissions. This is of significant importance for society and the environment considering that more than 15 million cars are manufactured every year in North America.
