A Study on the Design and Characteristic Analysis for Noise Cut Transformer |
| Abstract |
Broadband noise with frequency components in the range from several kHz up to tens of MHz is a major obstacle factor in normal operation of the AC line to supply the power to electrical and electronic control equipments. Because this kind of noise could damage the device or could be a source of malfunction, many devices such as filter and surge suppressor are used to cut off the noise. But those devices could not disconnected from the power line, so they result in poor common-mode reduction performance and are used in limited area. In this paper, we presented the design method of NCT as well as insulation characteristics as a isolation transformer in addition faraday shielding and proposed analysis model of NCT having two functions of surge and noise reduction. The simulated and experimental results for the surge suppression characteristics are compared and evaluated for designed protype 1[kVA] NCT. |
