Power Electronics Converters for Electric Vehicles

目前全球政府减少温室气体排放的激励措施刺激了电动汽车的发展。目前全球混合动力电动汽车的年产量约为500万辆，预计到2040年，这类汽车的数量将呈指数级增长，达到3000万辆。功率转换器是先进电动汽车(EVS)的主要部件。 不断上涨的能源成本和有害排放，加上化石燃料储量的不断减少，使得向电动汽车的过渡势在必行。高效、可靠地处理和存储电能是电动汽车在汽车市场上取得成功所需要解决的主要挑战之一。该项目涉及电动汽车电力电子技术的发展。这项研究计划的长期目标是将这些最先进的新技术商业化，并在电动汽车电力电子方面培训HQP。 虽然许多研究人员都在这一领域工作，但这项研究的创新之处在于所提出的替代现有变流器拓扑和控制技术的方案的独特性。这项拟议的研究是为开发具有工业重要性和学术意义的下一代电力电子技术而量身定做的。主要的重点是设计最小组件、高效和非常高的开关电路拓扑和数字控制技术，使半导体功率和控制电子设备能够集成在成本效益高和紧凑的电动汽车电源转换器中。 通过拟议的研究获得的先进解决方案将为加拿大工业渗透这一发展中的市场提供竞争优势。这种节能技术在电子信息、替代能源和航空航天领域的推广将进一步惠及加拿大，并有助于加拿大履行其在减少温室气体排放方面对《京都议定书》的承诺。

Current worldwide government incentives to reduce greenhouse gas emissions have spurred electric vehicle development. Global production of hybrid electric vehicles now totals approximately 5 million annually and it is expected that the number of such vehicles will grow exponentially, to 30 million by 2040. Power converters are the prime components in advanced Electric Vehicles (EVs). Rising energy costs and harmful emissions coupled with diminishing fossil fuel reserves are making the transition to electric vehicles imperative. Efficiently and reliably processing and storing electrical energy is one of the main challenges needing to be addressed to allow EVs to succeed in the automotive market. This program deals with the development of EV power electronics technologies. The long-term objectives of this research program are to commercialize these new state-of-the-art technologies and train HQP in power electronics for electric vehicles. Although a number of researchers are working in this field, the innovative character of this research lies in the uniqueness of proposed alternatives to existing converter topologies and control techniques. The proposed research is tailored for developing next generation power electronics technologies that have industrial importance and academic significance. The main emphasis is on devising minimum-components, highly-efficient and very-high switching circuit topologies and digital control techniques that enable the integration of semiconductor power and control electronics for cost-effective and compact power converters for electric vehicles. The advanced solutions obtained through the proposed research will provide a competitive edge to Canadian industries to penetrate this developing market. Proliferation of this energy-efficient technology in the electronic information, alternative energy and aerospace sectors will further benefit Canada as well as help Canada fulfill its commitment to the Kyoto Protocol in reducing greenhouse gas emissions.
