Switching mode power supply.

摘要

Switching mode power supply for supplying power to service equipment consuming heavy currents, in particular electrical welding equipment, in which the mains voltage is rectified by a mains rectifier, the direct voltage thus obtained is converted into a high-frequency square-wave voltage by means of semi-conductor switches controlled by high-frequency and the high-frequency square-wave voltage is transformed by a transformer and is rectified by an output rectifier, wherein the conductors of each electrical circuit carrying high-frequency power in the region between mains rectifier and output of the output rectifiers are formed as thin laminated metal plates having thin-film, preferably foil, insulation lying there-between.
