| Abstract(in English) | Fast switching increases the radiated noise, which is a problem that exceeds the regulation value of radiated emission test. In particular, when multiple switching power supplies are mixed, it has been difficult to identify the source of the noise because the noise overlaps in the same frequency band. In this study, we propose a method to estimate the far-field measurement waveform of each switching power supply module by identifying the noise source based on the periodicity of the pulses in the near field. In this paper, we propose a method to estimate the far-field measurement waveform of each switching power supply. |
