Design and Simulation of Discrete Controller for DC-DC Converter

Abstract

This paper describes boost converter with closed loop discrete Proportional, Integral and Derivative (PID) controller are designed and simulated. The dynamic performance of the boost converter can be improved by the design of discrete PID PWM controller. Discrete PI Controller, Analog PI & PID Controller of boost converter is designed and simulated whose performance parameters are compared with the Discrete PID Controller is illustrated. The DC–DC converter can withstand its regulation performance with the variations in input supply voltage, circuit inductance, capacitance and load resistance.
