220V To 12V Without Transformer. T1 converts a main 220V voltage down into 12V Then AC voltage current flows through to D1D4 to the fullwave rectifier into DC current And there is a C1 filter to DC voltage that smooth so well This circuit is a fullwave rectifier that center tap transformer and 2 diodes Also you can use a bridge rectifier without a center tap transformer and 4 diodes This current.
