| Abstract | It is widely recognized that electrostatic discharge (ESD) generators cause electromagnetic (EM) noises even before and after ESD immunity testing specified in the International Electrotechnical Commission (IEC) standard. This may provide inconsistent test results, whereas its mechanism is not well understood. To explain the mechanism qualitatively, the authors investigated a generation modeling of EM noises from an ESD generator in conjunction with the functional sequences of built-in relay switches and a DC high voltage power supply. To validate this model, using a magnetic field probe, the authors measure the induced noise voltages from an ESD generator just before and after ESD testing for contact and air discharges to an IEC recommended current injection target. As a result, it is confirmed that the EM noises are generated when the relay switches operate before and after ESD tests. In addition, the authors find that the noises amplitude for low voltages (Types C, D and F) are relatively smaller than the ones (Types A&B, E) induced at the testing in both the contact and air discharge modes, while these peak noises increase with charging voltages and especially the noise peaks induced after the testing reach almost the same level as the case for 4 kV ESD test in the air discharge mode. A new sequence of the built-in relay switch is also proposed for reducing the noise voltages generated after ESD testing. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
