| Abstract(in English) | International Electrotechnical Commission (IEC) specifies conducted immunity test wave as continuous wave (CW) in IEC 61000-4-16 or CW with pulse modulation in IEC 61000-4-19, which are supposed to simulate conducted disturbances below 150 kHz. However, it has not been clarified that these test waves consider the effect of pulse width modulation (PWM) or pulse frequency modulation (PFM), typical control method of power conversion equipment, such as rectifiers. For this reason, immunity test result with using the test waves might not evaluate the immunity of ICT equipment in actual usage environment. For creating new test waves which can evaluate immunity of ICT equipment in actual environment, authors have been discussed on the effect of the PWM/PFM to the conducted disturbance, and found that peak amplitude and peak frequency of the conducted disturbance fluctuated when the PWM/PFM are operated and proposed a numerical model of the immunity test wave which applies formula of amplitude modulation to express time fluctuation of peak amplitude, and formula of frequency modulation to express time fluctuation of peak frequency. In this work, authors verify the validation of the proposed model by conducted immunity evaluation with power line communication (PLC) system. As a result, it is f ound that the proposed wave, generated by waveform modeling, can evaluate the conducted immunity characteristics of ICT equipment in an actual usage environment more accurately than the conventional waves, CW or CW with pulse modulation. |
