Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...

A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.

Everyone loves a full-wave bridge rectifier, but there’s no denying that they aren’t 100% efficient due to the diode voltage drop. Which isn’t to say that with some effort we cannot create an ideal ...

In the realm of modern electronics, semiconductor diodes have emerged as fundamental components with diverse applications. One of their pivotal roles lies in the fields of rectification and voltage ...

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 ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Fig. 1. Typical diode full-wave bridge. Full-wave diode bridges are found in many electronic systems (Fig. 1). At typical AC power line voltages, the drop across the diodes has little impact on the ...
