Abstract

This study analysedthe characteristics of total harmonic distortion (THD) and output voltage ripple in a flyback PFC converter circuit under two different loads, which are the LED lamp modules and nonlinear RL loads. The converter was designed to step down the AC input voltage (90 V-265 V) to a DC output voltage of 80 V DC for both loads, each with an output power of 16 W. The main objectives were to observe and assess current THD and output voltage ripple for both loads using two different capacitances of the output capacitor, which are 2400 μF and 6 μF, respectively. The results demonstrated that using smaller capacitors(6 μF), it increased output voltage ripple, which it increased for the LED lamp load from 10% to 25% and for the nonlinear RL load it increased from 15% to70%. However, with the same smaller capacitors (6 μF), it reduced current THD for both loads, which for the LED lamp load it reduced from 12% to 10.3%, and for the nonlinear RL load it reduced from 13.7% to 8.3%. From these results, with 2400 μF of the output capacitor, it provided better performance in terms of current THD and output voltage ripple for both load types.

LED灯和非线性RL负载下反激式PFC变换器的电流、THD和输出电压纹波特性

研究了LED灯模块和非线性RL负载下反激式PFC变换器电路的总谐波失真和输出电压纹波特性。转换器设计用于将两个负载的交流输入电压(90 V-265 V)降压到80 V DC的直流输出电压，每个负载的输出功率为16 W。主要目的是观察和评估两种负载的电流THD和输出电压纹波，使用两种不同的输出电容，分别为2400 μF和6 μF。结果表明，采用更小的电容(6 μF)可以提高输出电压纹波，LED灯负载的输出纹波从10%增加到25%，非线性RL负载的输出纹波从15%增加到70%。然而，在同样小的电容(6 μF)下，它降低了两种负载的电流THD，其中LED灯负载从12%降低到10.3%，非线性RL负载从13.7%降低到8.3%。从这些结果可以看出，当输出电容为2400 μF时，在两种负载类型的电流THD和输出电压纹波方面都有更好的性能。

期刊介绍： The International Journal of Integrated Engineering (IJIE) is a single blind peer reviewed journal which publishes 3 times a year since 2009. The journal is dedicated to various issues focusing on 3 different fields which are:- Civil and Environmental Engineering. Original contributions for civil and environmental engineering related practices will be publishing under this category and as the nucleus of the journal contents. The journal publishes a wide range of research and application papers which describe laboratory and numerical investigations or report on full scale projects. Electrical and Electronic Engineering. It stands as a international medium for the publication of original papers concerned with the electrical and electronic engineering. The journal aims to present to the international community important results of work in this field, whether in the form of research, development, application or design. Mechanical, Materials and Manufacturing Engineering. It is a platform for the publication and dissemination of original work which contributes to the understanding of the main disciplines underpinning the mechanical, materials and manufacturing engineering. Original contributions giving insight into engineering practices related to mechanical, materials and manufacturing engineering form the core of the journal contents.
