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

本研究的目的是为插电式混合动力汽车（phev）开发一种20kW的新型集成双向转换器。集成转换器的组件更少，体积更小，更具成本效益。该方法是将AC/DC整流器和双向DC/DC转换器集成在插电式混合动力汽车的一个拓扑结构中。由于其高度复杂性和高度研究性，该问题尚未在任何插电式混合动力转换套件中得到解决。然而，该项目对国家的重大环境和经济效益使其成为一个合适的、及时的国家科学基金支持项目。该项目的智力优势在于设计、优化和开发集成双向转换器，通过出口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综合教育，研究和工程，以满足新兴劳动力和国家汽车工业的需求。项目团队将促进教育作为项目的一个组成部分。女性和少数民族研究生将参与拟议的项目。PI计划在他的教学课堂（ECE 764-车辆动力系统）中使用调查结果。该项目将开发更清洁、更高效的汽车，并培训工程师开发燃油经济性更高、排放更低的汽车，从而造福社会。考虑到北美每年生产超过1500万辆汽车，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.
