Simulation and Analysis of DC-DC Boost Converter Using Sliding Mode Controller under Variable Conditions
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 1
Abstract
As the requirement of power increases, it is required to increase the generation on demand. Now a days, solar PV and wind are increasingly used for generation. The power collected from these energy source need to be converted using DC-DC or AC- DC converters. The main converter used is Boost converter for step up this voltage. These sources are variable by nature, so problem arises is to maintain constant required output in all conditions. Boost converter converts the input voltage into higher value of voltage as per the input is received. This issue of obtaining constant output under variable conditions can be resolved by using sliding mode control of the converter. There are many theories to implement this technology with converter but the problem arises when the inductance and capacitance parameters changes as load varies. The proposed work is to resolve this problem by using sliding mode controller with modified values of parameters and beta factor for precise values using feedback, close loop system. The input source is taken as DC source voltage at variable conditions. The modeling is done in MATLAB/Simulink software.
