Current-sharing control technique of interleaved buck converter for automotive application

This paper presents control strategies for an interleaved converter in automotive application with a focus on the current sharing between cells and fault tolerant capability. The control strategies are based on PI controllers and explore different possibilities and configurations for controlling the interleaved converter. The interleaved converter is designed with optimization under multi physics constraints to find the optimal architecture with optimal number of cells and looking for the appropriate active and passive components technologies. The results of interleaved converter design are used in simulation to validate the control strategies. An experimental control is carried out to demonstrate the control feasibility.
