Pulse Shaping Method using Bridge Tap for Fast Transient Burst Test Generator
Authors: ,
Abstract: A fast transient phenomenon is observed when a power line circuit is switched on or off. To simulate this phenomenon, we use a fast transient burst test generator. Since the rise time of waveform generated by the fast transient burst test generator is very fast, a waveform distortion affects an immunity test result. Therefore, additional components such as resitor, capacitor and inductor are generally used for adjusting waveform when using a convetinal generator. It takes a long time to obtain an ideal waveform by trial and error. In this paper, a pulse-shaping method using bridge tap is proposed. It means that another coaxial cable having open circuit termination is added to the output terminal of the generator. We call this bridge tap method. The bridge tap is known that the performance is deteriorated. However, distortion can be decreased if it applies to the pulse that there is a distortion. By adjusting the length of the bridge tap depending on the distortion, the waveform can be controlled. This method has already beeing filed as a patent in Japan.
