Typically, a power supply is comprised of a power transformer, which is then followed by a conventional bridge rectifier. The bridge rectifier is constructed using four diodes that are interconnected ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...

comprise a transformer, rectifier, and filter capacitor. Many single-voltage power suppliesconsist of a transformer, arectifier, and a filter capacitor, as shownin Figure 1. This circuit is ...

Welcome back to this week’s installment of Scope Noob where I’m sharing my experiences learning to use my first oscilloscope. Last week I started out measuring mains frequency using an AC-AC wall wart ...

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 ...

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 ...
