摘要
与传统的Boost PFC变换器相比,交错并联Boost PFC可有效降低输入电流纹波和开关器件的电流应力,减少了前级EMI滤波器的尺寸,提高PFC电路的功率等级和效率;详细分析了交错并联Boost PFC电路的工作原理、主要的工作状态并搭建仿真平台进行验证,实验结果证明交错Boost PFC电路具有良好的功率因数校正效果。
Compared with the Boost PFC converter, interleaved Boost PFC is capable of reducing the input current rip- pie and the current stress of the switch, decreasing the EMI filter size, improving the power grade and efficiency. Therefore, the fundamental principles and the main operating condition of the interleaved Boost PFC are ana- lyzed in detail this paper, and verified through the emulated platform. The experimental results show that high power fac-tor can be achieved by the interleaved Boost PFC.
