Extreme performance battery charger technologies for transportation

在过去十年中，电池供电设备(便携式电子产品和交通系统)的使用出现了前所未有的增长，预计电池市场将以每年7.8%的速度增长，到2019年达到1200亿美元。特别是，电池驱动的交通系统(工业车辆、电动汽车、公共汽车、电动自行车)的使用将继续快速增长，为经济增长和可持续发展提供独特的机遇。**UBC和Delta-Q Technologies的Ordonz博士和Eberle博士合作的目标是为电动交通电池充电器开发下一代高效和智能的电源转换器。这一领域的进步将提高转换效率并降低成本，使消费者和公用事业提供商都受益。从消费者的角度来看，新的充电器将导致成本降低，从而刺激采用可持续的交通系统。从电力公司的角度来看，新型高效电池充电器将降低能源消耗，并有助于缓解电能质量问题。这项研究的目标是开发使用最先进的宽带隙半导体器件、同步整流和数字控制的尖端多谐振拓扑，预期结果是将充电器电路中的功率损耗减少一半。反过来，通过采用软开关、适用于高频工作的新颖电路设计，充电器的功率密度和竞争力将得到显著提高。该研发项目将帮助行业领先者和总部位于不列颠哥伦比亚省的Delta-Q公司保持相对于国际竞争对手的竞争优势。**该项目与不列颠哥伦比亚省政府的清洁能源目标直接一致，不列颠哥伦比亚省政府已承诺为这些研发活动提供10万美元。该项目将使UBC能够为未来的工程师提供替代电力转换方面的培训。该项目非常及时，因为它预计到替代能源领域对工程师的高需求。

Over the past decade, there has been an unprecedented growth in the use of battery-powered equipment (portable electronics and transportation systems) and the battery market is expected to increase by 7.8% per year to $120 billion by 2019. In particular, the adoption of battery-powered transportation systems (industrial vehicles, EVs, buses, e-bikes) will continue to increase rapidly, presenting a unique opportunity for economic growth and sustainable development.**The objective of the collaboration between Drs. Ordonez and Eberle at UBC and Delta-Q Technologies is to develop the next generation of high efficiency and smart power converters for electrified transportation battery chargers. Advances in this area will improve conversion efficiency and reduce costs, benefitting both consumers and utility providers. From the consumer's perspective, novel chargers will result in cost reductions, thereby stimulating the adoption of sustainable transportations systems. From the utility's perspective, novel high efficiency battery chargers will reduce energy consumption and help mitigate power quality issues. The research targets the development of cutting-edge multiresonant topologies using state-of-the art wide-bandgap semiconductor devices, synchronous rectification, and digital control with the anticipated outcome of cutting power losses in the charger circuits in half. In turn, the charger's power density and competitiveness will be improved substantially by employing soft-switching, novel circuit design for high frequency operation. The R&D project will help industry leader and BC-based Delta-Q maintain a competitive advantage over international competitors.**The project aligns directly with the clean energy objectives of the Government of British Columbia, which has committed $100,000 towards these R&D activities. The project will enable UBC to provide training to future engineers in alternative power conversion. The project is very timely since it anticipates the high demand for engineers in alternative energy.
