Renewable energy based interleaved boost converter

Abstract

Nowadays, there is a demand to increase the power generation capacity because of steadily rising electrical energy consumption. In order to achieve this, renewable energy sources are the best option. Among all the renewable energy sources, solar power generation system tops the list. For increasing the output of these sources we need a suitable boost converter. Interleaved boost converter (IBC) is one of such converter which consists of several identical boost converters connected in parallel and controlled by interleaved method, which has same switching frequency and phase shift. The advantages of using IBC over conventional boost converter are increased efficiency, improved reliability, reduced current peak value and these converter cells have good current sharing characteristics. The proposed method provides the increased output voltage along with efficiency. Here, in this work we have also shown the application of IBC in running BLDC motor. To detect the position of BLDC motor hall sensors are used. The proposed strategies have been verified with the help of MATLAB/SIMULINK along with the hardware implementation.
