ANALYSIS AND DESIGN OF DIGITAL PID CONTROLLER FOR PUSH-PULL DC/DC CONVERTER

Abstract

This paper presents a method for the design and simulation of digital controller based on Field Programmable Gate Array (FPGA) technique for DC/DC Push-Pull converter operating in continuous conduction mode. The Push-Pull converter is simulated using PSIM and controller is designed using MATLAB with the help of XILINX tool box. Using SimCoupler module in MATLAB, co-simulation of PSIM and MATLAB is obtained. The performance of FPGA based PID controller strategy is validated for line and load variations.
