| Abstract(in English) | An immunity testing method for electrostatic discharge (ESD) is being specified in IEC 61000-4-2, in which the contact discharge of an ESD-gun is being normally specified. Air discharge testing is known to be a severe immunity test compared to the contact discharge testing, while the discharge current injected is not well reproduced. Grasping the behavior of the current injected by the air discharge would be helpful in establishing the worst-case ESD immunity testing. We thus previously measured the discharge currents for air discharge testing onto the IEC recommended current transducer with a commercially available ESD-gun, and showed that there exists a specific relationship of I_p・t_r^ξ/V_c=constant(ξ<1), between rise time t_r and current peak I_p. The current transducer, however, has frequency dependent transfer impedance, which should affect the measured current waveform. In this study, we proposed a method for estimating the discharge current from simultaneously measured magnetic fields with two magnetic probes. With this method, we estimated the discharge currents for air discharge testing onto a ground plane. As a result, we could confirm the existence of the above-mentioned relationship. |
