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.
