Abstract: This paper introduces interleaved boost converters topology for PFC (power-factor-corrected), which has continuous input current that you can manipulate with average-current-mode-control techniques to force input current to track changes in line voltage. The concept of interleaving, or more generally that of increasing the effective pulse frequency of any periodic power source by synchronizing several smaller sources and operating them with relative phase shifts. With the help of the interleaving technology the inductor current of interleaved boost converter can be reduced and thus inductor size is reduced. The Zero voltage technique provides perfect turn on process of the converter . There is no overlap between the voltages and current, hence no switching loss takes place at turn on process. The performance of proposed work is tested and verified by MATLAB/SIMULINK software.
Keywords - interleaved boost converter, power factor correction (PFC), switching loss, zero-current switching (ZCS), zero-voltage switching (ZVS).
