Performance Analysis of Solar MPPT (InC Algorithm) Based Three Phase Interleaved Boost Converter using Coupled Inductor for Brushless DC Motor

Interleaving strategies in power DC-DC converters are gaining ever-increasing importance due to its enormous advantages. Interleaved converter having coupled inductor plays a significant role for minimizing the voltage and current ripples. This paper presents the performance of brushless DC motor fed from solar energy using coupled inductor three phase interleaved boost converter. This converter circuit is controlled by incremental conductance algorithm. The difference between uncoupled and coupled inductor three phase interleaved boost converter are presented. It is found that the output wave forms of coupled inductor three phases interleaved boost converter fed brushless DC motor are smoother than three phases interleaved boost converter fed brushless DC motor. Simulation and analysis of the system are carried out through MATLAB/Simulink.
