摘要

大多数AC-DC系统包括一个用于功率因数校正的AC-DC转换器，然后是一个隔离的DC-DC转换器。交直流变换器的输入电流波形中含有非线性元素，会产生谐波，因此需要一种合适的控制技术来平滑输入电流以减少谐波。对于大功率应用，无桥交错(bll) AC-DC转换器是首选。本文对可用于功率因数校正的不同控制技术进行了比较。并与电源电流、电源畸变因数和电源功率因数的THD进行了比较。在MATLAB/SIMULINK环境下，采用多种控制技术对bll变换器进行了仿真，并给出了仿真结果。

A comparative study on different control techniques on bridgeless interleaved AC-DC converter for power factor correction

Most of the AC-DC systems include an AC DC converter for power factor correction followed by an isolated DC-DC converter. AC-DC converters will introduce harmonics to the input current waveform as it contains nonlinear elements, so a suitable control technique is required to smoothen the input current to reduce harmonics. For high power applications, Bridgeless interleaved (BLIL) AC-DC converter is a preferred choice. In this paper, a comparison of different control techniques that can be used for power factor correction is presented. The comparison is done with THD of supply current, supply distortion factor and supply power factor. Simulation of a BLIL converter is carried out in MATLAB/SIMULINK environment using various control techniques and the results are presented.
