Designing a switch-mode power supply.

Since the subject of this thread is discussed in other threads in these fora, I suggest readers follow other more mature threads which have already tried and tested schematics. The following link is about a full bridge SMPS driven directly from rectified 230V AC mains.

To Moderators and Administrators:
This thread can be deleted as it is only an attempted replicate of information which is already available in these fora. Unlike what some wrote, SMPS discussion on these fora is NOT a taboo. Some members DID build and design powerful SMPSs.
