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级增长。到2022年，该行业的全球市场预计将达到188亿美元。电池充电器被广泛应用于各种不同的产品中，如汽车、信息技术、电信等。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级增长。因此，对高性能低成本电池充电器的需求是巨大的。高效率、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，并带来更清洁的环境。**本质上，电池充电器将来自公用电网的交流电源转换为直流电源，以便为电池充电。**现有的电池充电器通常采用两级功率转换系统，以便进行交流到直流**转换。两级功率转换效率低，功率密度低，成本高。因此，**它们不能满足未来电池充电应用的要求。**本研究的主要目的是为**汽车行业的电池充电器设计和开发卓越的解决方案。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。拟议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，为该应用提供高效和低成本的解决方案。这项研究旨在提供高性能的“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。该研究项目将通过为汽车行业提供高性能电池充电器，直接使Delta-Q和加拿大能源部门受益。

Battery charging industry has recently experienced an exponential growth due to the increasing demand for**battery-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 as**automotive, information technology, telecom, etc. In particular, very high demand from the automotive**industry has driven the exponential growth of the global battery charging market. Thus, there is a tremendous**need for high performance low-cost battery chargers. Innovative battery charging solutions with high efficiency**and low cost can disrupt the market and have a huge impact on the automotive industry. Highly efficient**battery chargers can not only generate substantial revenue for the economy, but will also save energy and result**in 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 DC**conversion. 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 in**automotive industry. The proposed solutions are based on single-stage power conversion, which can offer**higher efficiency and lower cost. The proposed battery chargers take advantage of recent advances in high**frequency power electronic technology and digital control systems in order to offer highly efficient and**low-cost solutions for this application. This research aims to deliver "next-generation" single-stage battery**chargers with high performance. Delta-Q is well positioned to commercialize the next-generation high**performance battery charger products. This research program will directly benefit Delta-Q and the Canadian**energy sector by providing high performance battery chargers for the automotive industry.
