Compared with the traditional Boost PFC converter,the interleaved Boost converter effectively reduces the current stress of switches,the input current ripple and the size of the magnetic components.Based on the introduction of the interleaving technique,the work mode of the interleaved Boost converter is analyzed.The design principle of the inductor is derived in theory and the optimal methods of choosing power components are given with detailed loss analysis.The experimental results show that the interleaved Boost PFC converter is simple and has the advantage of high power factor and high efficiency.
