An electrical bus bar is an integral part of the electrical power distribution system. Do you know that a bus bar system distributes electric power in a multi-story building? This article details bus bars with their types and applications.

Embedded systems are more ubiquitous than we realize, but what exactly are they, and where are they used? This article compares embedded systems to desktop/laptop PCs, considers their advantages and disadvantages, and looks at some applications and examples.

With CPUs and GPUs getting smaller and smaller, high-power devices continue to have a large surface area and weight. Thyristors, one of the heaviest semiconductor devices, were invented in 1956. Are they still relevant in the market? Check out the article to learn more about the thyristor market in detail.

All transistors can become amplifiers but all amplifiers are not transistors. MOSFET amplifiers are types of FET small signal linear amplifiers. The article explains MOSFET amplifier types with their circuit diagram and AC equivalent representation. It explains the MOSFET amplifier operating through the common source configuration.

This article details the main calculations required for the design of a simple single-stage MOSFET amplifier. It reveals key parameters such as transconductance, drain current, and voltage gain, considering the amplifier's operation in its active region and applying basic circuit analysis concepts. Without considering thermal aspects that influence the calculations or attempting to address the circuit implementation for building an application, the example offers an interesting introduction to the operation of an enhancement-mode MOSFET amplifier.

Supercapacitors, or supercaps in short, are fast, powerful energy storage devices. They complement the relatively slow (dis-)charging batteries in numerous applications ranging from electric cars to industrial machines and wind turbines. A team of Empa researchers wants to develop better supercaps based on graphene – and make them ready for large-scale commercial production.

A light emitting diode (LED) is one of the most widely used semiconductor devices. Made from compound semiconductors, LEDs efficiently convert electrical energy into light. This article outlines their construction, working principle, operation, and main types in detail.

Just like power transistors and power diodes, thyristors are another important type of power semiconductor device. Thyristors are among the largest and heaviest semiconductor devices that can handle large amounts of power, something that transistors cannot do. The article talks about thyristors in detail, including their construction, types, operation, advantages, and disadvantages.

Photodiodes are important optoelectronic devices that serve various applications like photodetectors, photomultiplier tubes, cameras, and many more. Opposite to LED, photodiodes convert optical energy into electric current. The article explains photodiodes and working principles in detail.

Varactor diodes, also known as varicaps, integrate diodes and capacitors. Researchers invented them six decades after the diode and two centuries after the development of the capacitor. These small components act like capacitors in high-frequency and power applications. The article explains varactor diodes and their operation, advantages, disadvantages, and applications.
