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

In the previous article, you learned about the half-wave rectifier. It uses only one half of the AC input signal, which results in lower rectification efficiency and high ripple in the output. Due to these drawbacks, it is not suitable for applications requiring a stable and smooth DC output. To overcome these limitations, a full-wave … Read more

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
