This paper presents the effects of high amplitude conducted interference pulses on a switch mode power supply (SMPS). The interference injection is performed in differential mode and the interference amplitude is increased until the power supply destruction. These destruction tests are performed on different topologies of SMPS input filter. Then, all the destroyed SMPS components are analysed and measurements are performed to better understand the destruction mechanism. All this knowledge is finally used to build a behavioural model able to predict the destruction of the power supplies.Read less <
