Analysis the performance of interleaved boost converter

Abstract

The power DC-DC converter has been focused as a very important part in the form of different topologies in various applications. To overcome the major disadvantages of DC-DC power converters such as high voltage and current ripples, low efficiency etc, interleaving strategies play a significant role. The interleaved boost converter offers many advantages such as minimum voltage and current ripples, low switching loss, higher efficiency etc compared to traditional boost converter. To enhance the entire performance of the converter, ‘n’ numbers of paralleled converters are connected in the interleaved boost converter. The performance of interleaved boost converter with multiple phases is analyzed in this paper. Simulation and analysis of interleaved boost converter with multiple phases(two, three and four) are carried out through MATLAB/Simulink.
