In the previous article, you learned about the centre-tapped full-wave rectifier, but it works only with a centre-tap transformer. It makes the design bulkier and inconvenient in many applications. The bridge rectifier solves this limitation by using four diodes, which allows full-wave rectification without the need for a centre-tapped transformer. In this article, you will … Read more
A full-wave rectifier is an electronic circuit that converts an alternating current (AC) signal into pulsating direct current (DC) by utilizing both the positive and negative half-cycles of the AC input waveform.
In the previous article, you learned that a diode allows current to flow in only one direction. Now, we will use this principle to build a rectifier circuit that converts an AC signal into a DC signal—specifically, a half-wave rectifier. In this tutorial, you will learn the working principle of a half-wave rectifier, its circuit … Read more
In electronics, some components quietly do most of the heavy lifting without getting much attention. The diode is one of them. From converting AC to DC in power supplies to protecting sensitive circuits, emitting light, sensing light, and even generating laser beams, diodes are everywhere. For an engineering student, understanding diodes is non-negotiable. They appear … Read more
