Usually you will find an input bridge rectifier followed by an H bridge followed by an output transformer with slightly more turns on the secondary than the primary to boost voltage enough to allow a regulated output even when the input is at low line. Rectified output for DC of course and filter. Current feedback protection is recommended also, sometimes in the form of measuring the current in the lower section of the H bridge.

Ha ha, yes it is now i see that. If it is DC input then there is no need for input rectification. The input bridge rectifier would only be needed with an AC input.
