In this paper, it is shown how winding proximity effect losses in an existing AC inductor can be reduced without changing the actual winding. Instead, the core dimensions are changed with significant effects. For this purpose, Maxwell (ANSOFT) electromagnetic software package is used to investigate flux patterns and their influence on eddy current losses in the windings. Various core dimensions are...
Some of the components used in switch-mode power converters, such as inductors and transformers, may cause substantial power loss when switching frequency is largely increased. If extra heat dissipation or decreased efficiency is not acceptable, one needs to search for a method of reducing power loss. With higher switching frequency, inductors and transformers are commonly implemented with traces...
