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.
