Modeling and control of interleaved buck converter for electric vehicle fast chargers

This paper describes in details a three leg interleaved buck converter designed to electric vehicle fast charge stations. A different approach for the current control is presented, in which total output current control is decoupled from the circulating current control. In addition, the impact of the sampling and the discrete model are discussed aiming a discrete time implementation. Finally, the theoretical results are validated in a hardware in the loop (HIL) implementation.
