Simulation of Bi-directional DC-DC Converter Using FPGA

The basic idea of proposed system is to utilize the renewable resources by digital PWM control of Bi-directional DC – DC converter. Usually PWM pulse is being generated through a digital system such as microcontroller or Digital signal controller. In stand – alone application these controllers increases the cost but XILINX FPGA based PWM generation reduces the cost. XILINX FPGA is programmable device developed by XILINX which is being considered as an efficient device for rapid prototyping and also to perform concurrent operations. In this paper two PWM signals was generated to control the switch duty cycles in Bi-directional DC-DC Converter. In addition to that different modes of operation of the proposed circuit are verified by MATLAB / SIMULINK.
