摘要
提出了一种单相并联交错Boost PFC电路,升压电感采用分立式电感。详细论述电感电流断续模式下的Boost PFC交错并联电路,减小单个电感容量和前级EMI滤波器尺寸,提高PFC电路的功率等级和效率。仿真与实验结果表明,该PFC电路具有良好的校正效果,较小的输入电流纹波,较低的开关应力。
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 redueing 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.
