Teardowns of cheap electronic devices can produce results that are interesting, horrifying, or both, especially when mains power is involved. [bigclivedotcom] gave a minimalist LED lamp his reverse ...

The more common approach to manipulate the incoming AC wave so that both halves are used to cause output current to flow in the same direction is the use of full-wave rectifiers. A full-wave rectifier ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...
