本論文以返馳式電源供應器(Flyback Converter)作為LED之定電流驅動源電路,並搭配不連續導通模式及選用IC BCD SEMICONDUCTOR CORPORATION AP1680K6TR-G1為主要元件。為了改善該IC特性,低功率因數及高電流總諧波失真率的缺點，在線路增加功率因數修正電路架構,使得功率因數明顯提升0.234及電流總諧波失真率明顯下降54.27%,再針對電路架構利用田口方法進行品質設計改善,以達到最佳化49.68%並符合EN 61000-3-2。This thesis uses a Flyback Converter power supply as the LED constant drive source circuit,collocating discontinuous conduction mode and choosing IC BCD SEMICONDUCTOR CORPORATION AP1680K6TR-G1 being the main component.In order to improve the shortcomings of the low power factor and high current total harmonic distortion (THD) of this IC,by increasing the power factor circuit architecture in the circuit, the power factor was improved significantly by 0.234 and the current total harmonic distortion (THD) was decreased significantly by 54.27%.Finally, use the Taguchi method on the circuit to conduct quality design to achieve optimization of 49.68% and conform EN 61000-3-2.
