Abstract
A method for planar transformer with an odd turn ratio includes: determining a turn ratio and winding parameters of a transformer to be manufactured; if the turn ratio is odd, determining that there is respectively one winding turn on a first middle layer and a second middle layer and two winding turns on a top layer and a bottom layer; determining widths of winding wires on marginal layers as well as widths of winding wires on middle layers; winding and parallelly connecting an inner winding wire on the top layer to an inner winding wire on the bottom layer, and then serially connecting the parallel-connected inner winding wires to an outer winding wire to form a primary winding; and parallelly connecting the winding wire on the first middle layer to the winding wire on the second middle layer to form a secondary winding, so as to obtain the transformer.
