In power electronics, the SCR, DIAC, and TRIAC are three common semiconductor devices that are very useful in electric power control and conversion applications. Though they all belong to the thyristor family, their operation, structure, and applications differ significantly. Here’s a detailed explanation of SCR (Silicon Controlled Rectifier), DIAC (Diode for Alternating Current), and TRIAC […]
Dual power supply circuit is the backbone of many electronic systems. Various circuits, especially those involving operational amplifiers, analog devices, and certain digital systems, require both positive and negative voltages to operate properly. This is where Dual Power Supply Circuits come into play. They provide symmetrical voltages (like +12V and -12V, +15V and -15V, etc.) […]
Data transmission is the fundamental process of transferring digital or analog data between two devices. It plays a vital role in telecommunications, networking, computer architecture, and embedded systems. Two primary methods of data transmission are Synchronous and Asynchronous Transmission. Understanding their differences, working principles, and applications is crucial for designing efficient communication systems. Table of […]

Driveway lighting serves a dual purpose, enhancing both safety and aesthetics for your home. With the right lights, you can boost your home’s curb appeal while also ensuring a secure environment for both pedestrians and vehicles. Outdoor lights not only make your home more inviting but also act as a deterrent against potential intruders by […]
The term “Piezo” in Piezoelectric Transducer originates from the Greek word piezein, meaning “to press” or “to squeeze.” This etymology reflects the fundamental principle of piezoelectricity—a phenomenon in which mechanical pressure generates an electrical voltage. Piezoelectric transducers (sensor / Actuator) harness this effect to convert mechanical energy (such as pressure, force, vibration, or acceleration) into electrical […]
