The single-phase interleaved parallel Boost PFC circuit is adopted to improve the power grade and efficiency.The discrete inductor is used as a boost inductor.The operation experiment and simulation of interleaved parallel Boost PFC circuit were conducted uner the intermittent mode of inductance current.The interleaved parallel Boost circuit is capable of reducing the inductance capability and EMI filter size.The simulation and experimental results prove that the PFC circuit can realize good correction effect with small input current ripple and switching stress.
