Abstract:Understanding what causes a voltage spike is fundamental to designing robust electronic systems and ensuring their electromagnetic compatibility (EMC). Voltage spikes, also known as transients or surges, are brief, high-energy disturbances that can degrade insulation, corrupt data, or cause catastrophic failure in electrical and electronic equipment. This paper examines the primary physic...
Abstract:Understanding what is artificial network in EMC testing is fundamental to conducting reproducible conducted electromagnetic interference (EMI) measurements. An artificial network, also known as a line impedance stabilization network (LISN), provides a standardized impedance interface between the power mains and the equipment under test (EUT). This paper presents a technical analysis of ar...
Abstract: What is pulse magnetic field immunity? Pulse magnetic field immunity refers to the ability of electrical and electronic equipment to maintain normal functionality when subjected to transient, high-intensity pulse magnetic field interference. It is one of the key test items in the field of Electromagnetic Compatibility (EMC). This article systematically elaborates on the physical mechanis...
