摘要

本研究的重点是对电动自行车应用具有吸引力的单相 Cuk 和 SEPIC 功率因数校正转换器。为了保证性能的提高，所提出的改进型转换器被设计为在不连续传导模式下运行，这种模式不受电源和负载电压变化的影响。在额定负载情况下，调查研究降低了输入线路总谐波失真和功率因数。线路调节、高效率和负载调节是通过具有电压传感器和电流环路的闭环 PI 控制电路实现的。使用 MATLAB/Simulink 对各种工作条件下的电源进行了仿真，并使用 250 W 硬件原型对所设计的系统进行了验证。观察到输入电流为完全正弦波，并按照 IEC 61000-3-2 A 级标准记录了电源电流的总谐波失真。

Bridgeless modified Cuk–SEPIC power factor correction converter for E-bicycle applications

The focus of this scope is on the single phase Cuk and SEPIC power factor correction converter that is attractive to electric bicycle applications. In order to guarantee improved performance, the proposed modified converter is designed to operate in discontinuous conduction mode, which is hidden by changes in supply and load voltage. For rated load, the investigational study achieves reduced input line total harmonic distortion and unity power factor. Line regulation, high efficiency, and load regulation are achieved by means of a closed loop PI control circuit that has a voltage sensor and current loop. The power supply is simulated using MATLAB/Simulink under various operating conditions, and the designed system is validated using a 250 W hardware prototype. The input current is observed to be perfectly sinusoidal, and the IEC 61000-3-2 class A standard is followed in recording the total harmonic distortion of the mains current.
