The Effect of the Transformer Winding on the Reliability of Switching Power Supplies

Abstract

Today reliability is one of the serious requirements of electronic systems, and, using that, the number of system failures, repair cost, guarantee, etc are estimated by this factor. In this paper, the reliability of a switching power supply (SMPS) is evaluated and the effect of the type of transformer winding on the reliability is fully discoursed. It is proven that the interleaved winding will increase the reliability of SMPS's.
