In this paper, the problem related to transformation of ac voltage into DC voltage used in tram supply is considered. A variable component is always present in rectified voltage. Pulsation of rectified voltage is influenced by different factors. In a 12-pulse system, where two secondary transformer windings are used (one delta-connected and the other star-connected), an additional factor increasing the pulsation is the unbalance of the output voltages at these windings. Tap changer may be used and its setting is optimized here by applying the ant-colony algorithm. Different supply voltage variants have been considered. It is demonstrated that pulsation may be reduced by even 25%.
