Abstract :
The high-frequency transformer design for switch mode power supplies consists of core and winding design. It is necessary to take the cost of power loss and core volume in the long term into consideration during selection of core size, shape and material to produce an efficient transformer. The proximity effect seen in the windings deteriorates the performance of the transformer and can be averted by using Litz wires and sandwich winding structure.
