摘要:

针对常规Boost变换器的开关器件电压应力过大的问题,研究了交错并联Boost变换器。首先对交错并联Boost功率因数校正(PFC)电路在减小输入电流纹波、电感磁芯尺寸和输出电容电流方面上的优势进行推导;然后对变换器主电路的关键参数进行设计,设计基于平均电流控制的双闭环控制系统;最后仿真实验验证。结果证明交错并联Boost变换器在大功率场合中既能很好地实现PFC,又能有效地降低功率器件的电流应力、减小输入电流纹波和电感磁性元件的体积,提升功率等级。

Abstract:

In response to the problem of excessive voltage stress in the switching devices of conventional Boost converters,the interleaved parallel Boost converters were studied.Firstly,the advantages of interleaved parallel Boost power factor correction(PFC) circuits in reducing input current ripple,inductor core size,and output capacitor current were derived.Then,the key parameters of the main circuit of the converter,and a double closed-loop control system based on average current control were designed.Finally,it was verified by the simulation experiments.The results show that the interleaved parallel Boost converters can not only achieve the power factor correction well in high-power situations,but also effectively reduce the current stress of power devices,the input current ripple and the volume of inductor magnetic components,and improve power levels.

Key words: interleaved parallel connection, power factor correction(PFC), ripple, voltage stress
