Extreme performance battery charger technologies for transportation

在过去的十年中，电池供电设备（便携式电子设备和运输系统）的使用出现了前所未有的增长，预计到2019年，电池市场将以每年7.8%的速度增长，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）的采用将继续迅速增加，为经济增长和可持续发展提供了独特的机会。**博士之间合作的目的。UBC的Ordonez和Eberle以及Delta-Q Technologies将为电气化运输电池充电器开发下一代高效智能电源转换器。这一领域的进步将提高转换效率，降低成本，使消费者和公用事业供应商都受益。从消费者的角度来看，新型充电器将降低成本，从而刺激可持续交通系统的采用。从公用事业的角度来看，新型高效电池充电器将减少能源消耗，并有助于缓解电能质量问题。该研究的目标是利用最先进的宽带隙半导体器件、同步整流和数字控制开发尖端的多谐振拓扑结构，预期结果是将充电器电路的功率损耗降低一半。采用软开关和新颖的高频工作电路设计，将大大提高充电器的功率密度和竞争力。该研发项目将帮助行业领导者和总部位于bc的Delta-Q保持相对于国际竞争对手的竞争优势。**该项目直接符合不列颠哥伦比亚省政府的清洁能源目标，该政府已承诺为这些研发活动提供10万美元。该项目将使UBC能够为未来的替代能源转换工程师提供培训。这个项目非常及时，因为它预见到替代能源对工程师的高需求。

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.
