MODELING, DESIGN, AND CONTROL OF ASYNCHRONOUS BUCK CONVERTER FOR MOBILE APPLICATION
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 10
Abstract
The aim of this paper is to model and design an open-loop and close-loop asynchronous Buck switching converter for mobile applications. The design of the converter is performed to step-down the input voltage 12V to an output voltage of 5V and current of 2A. The converter performance such as load voltage, capacitor and inductor currents, voltages and currents ripples, etc. are derived under continuous and discontinues operation. The Matlab/Simulink program is used to simulate the converter operation and the waveforms of circuit parameters are carried out. Due to changes in the supply voltage or circuit parameters, there is deviation of the circuit operation from the desired nominal performance. So a close-loop PID controller is designed such that any input variations produce a constant desired output voltage and current.
