在本文中，蜂群优化（BCO）算法适用于谢泼德-泰勒变换器功率因数（PF）校正的电流控制策略。该控制方法旨在消除转换器中的输入电流谐波。 BCO算法是一种新型的基于群体的搜索算法，是基于群体智能的元启发式技术之一。该算法依赖于对真实蜜蜂的自然行为进行建模。在这种方法中，Sheppard-Taylor 转换器开关的 BCO 算法生成占空比，以获得单位 PF (UPF) 和较低的输入电流总谐波失真。计算半个线路周期的占空比并将其存储在查找表中。通过将存储器与线路同步，可以在工作点实现接近统一的 PF。前馈也被用于具有输入电压最大值的控制算法中。前馈的实施提高了转换器的性能。转换器的输入电流工作在连续导通模式下。仿真和实验结果表明，所提出的控制策略效果良好，并且可以在宽输入电压、负载和参数变化的情况下实现UPF。结果符合国际电工委员会 (IEC) 61000-3-2 电流谐波标准。
In this paper, a bee colony optimization (BCO) algorithm is adapted to the current control strategy of power factor (PF) correction for a Sheppard–Taylor converter. The control approach is developed to eliminate the input current harmonics in the converter. The BCO algorithm is a new population-based search algorithm which is one of the metaheuristic techniques based on swarm intelligence. This algorithm depends on modeling the natural behavior of real honey bees. In this approach, duty cycles are generated by the BCO algorithm for the Sheppard–Taylor converter switch to obtain unity PF (UPF) and lower total harmonic distortion of the input current. The duty cycles for half a line period are calculated and stored in a lookup table. By synchronizing the memory with the line, near-unity PFs can be achieved in an operating point. The feedforward is also used into the control algorithm with the maximum value of the input voltage. The implementation of feedforward improves the converter performance. The input current of the converter is operated in continuous conduction mode. The simulation and experimental results show that the proposed control strategy works well and the UPF can be achieved with wide input voltage, load, and parameter variation. The results are compatible with the International Electrotechnical Commission (IEC) 61000-3-2 current harmonic standard.
