| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | As the LED lightning equipment is widely used on the several places, wiring structure of the power line is different at each place. In this study, current noises flowed on three kind of wiring structure, such as cascade, branch and extended switch line of branch models are discussed. The peak frequency of current on branch model is shift higher than that of cascade model. In addition, amplitude of branch model is also increased. The cause of the frequency shift is that the line length from LISN is shorter than the cascade model. In addition, because there are multiple power lines with different lengths, peak frequencies at each power line are added, and peak current width is become wide band. When the length of line extended to the switch that turn ON/OFF the LED bulb is varied, current noise is decreased that that of the branch model. By extending the power line, it is possible to decrease of the current noise. |
