New Single-Stage AC/DC Converters for Battery Chargers

由于对电池供电设备、车辆和机器的需求不断增加，电池充电行业最近经历了指数增长。到2022年，该行业的全球市场预计将达到188亿美元。电池充电器用于汽车、信息技术、电信等不同应用的各种产品中，特别是汽车行业的高需求推动了全球电池充电市场的指数增长。因此，迫切需要高性能低成本的电池充电器。具有高效率和低成本的创新电池充电解决方案可以颠覆市场，并对汽车行业产生巨大影响。高效率的电池充电器不仅可以为经济带来可观的收入，还可以节省能源，从而产生更清洁的环境。本质上，电池充电器将来自公用电网的交流电转换为直流电，以便为电池充电。现有的电池充电器通常使用两级电源转换系统，以便执行AC到DC转换。两级功率转换导致低效率、低功率密度和高成本。因此，他们不能满足未来的电池充电应用的要求。本研究的主要目标是设计和开发上级解决方案，电池充电器用于汽车行业。所提出的解决方案基于单级功率转换，可以提供更高的效率和更低的成本。所提出的电池充电器利用高频电力电子技术和数字控制系统的最新进展，以便为该应用提供高效和低成本的解决方案。本研究旨在提供具有高性能的“下一代”单级电池充电器。Delta-Q在下一代高性能电池充电器产品的商业化方面处于有利地位。这项研究计划将通过为汽车行业提供高性能电池充电器，直接使Delta-Q和美国能源部门受益。

Battery charging industry has recently experienced an exponential growth due to the increasing demand forbattery-powered devices, vehicles, and machines. The global market for this industry is projected to reach$18.8 billion by 2022. Battery chargers are used in a wide variety of products for different applications such asautomotive, information technology, telecom, etc. In particular, very high demand from the automotiveindustry has driven the exponential growth of the global battery charging market. Thus, there is a tremendousneed for high performance low-cost battery chargers. Innovative battery charging solutions with high efficiencyand low cost can disrupt the market and have a huge impact on the automotive industry. Highly efficientbattery chargers can not only generate substantial revenue for the economy, but will also save energy and resultin a cleaner environment.Essentially, battery chargers convert AC power from the utility grid to DC power in order to charge a battery.Existing battery chargers usually utilize a two-stage power conversion system in order to perform AC to DCconversion. Two-stage power conversion results in low efficiency, low power density, and high cost. Thus,they cannot satisfy the requirements of future battery charging applications.The main objective of this research is to design and develop superior solutions for battery chargers used inautomotive industry. The proposed solutions are based on single-stage power conversion, which can offerhigher efficiency and lower cost. The proposed battery chargers take advantage of recent advances in highfrequency power electronic technology and digital control systems in order to offer highly efficient andlow-cost solutions for this application. This research aims to deliver "next-generation" single-stage batterychargers with high performance. Delta-Q is well positioned to commercialize the next-generation highperformance battery charger products. This research program will directly benefit Delta-Q and the Canadianenergy sector by providing high performance battery chargers for the automotive industry.
