Xilinx System Generator-Based FPGA Control of Power Flow for DC/DC Converter

In recent years, Xilinx system generator platform (XSG) is becoming more popular in real-time simulations. This is especially true for applications involving FPGA as controllers such as power electronic converter control. Since XSG is integrated with MATLAB/Simulink, it eliminates the need of special skills in VHDL or HDL and enables the user to design control techniques with the help of Xilinx block sets and to test these control designs simultaneously. This paper aims to design the power flow control method in dual active bridge (DAB) bidirectional DC/DC converter using XSG for real-time simulation and to verify the control strategy. The result obtained through XSG-based hardware-in-the-loop (HIL) simulation is helpful to know the controller performance a priori in real-time implementation.
