What is a Buck Boost Converter? The buck–boost converter is a type of DC-to-DC converter (also knownas a chopper) that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is used to “step up” the DC voltage, similar to a transformer for AC circuits. It is … Read more
What are Fiber Optics Cables Used For? Fiber optic cables (also known as optical fiber cable) are network cables that contain many strands of fine glass fibers known as optical fibers, which are kept well-insulated within the body of the cable. These cables are created for the use of long-distance, high-performance data networking, and telecommunications. … Read more
Synchronous motors are defined as constant speed motors that run at the synchronous speed of the supply. They are typically used for constant speed operations and to improve the power factor under no load conditions. Synchronous motors also have fewer losses compared to induction motors of the same rating.The speed of a synchronous motor is … Read more
The Physics of a Semiconductor There are some materials, which have neither good conductivity nor bad conductivity of electricity. They have a moderate range of electrical conductivity. The examples of such materials are germanium, silicon, carbon etc. As the conductivity of those materials lies between good conductors and insulators, and these materials are called semiconductors. … Read more
Depending on the construction of its magnetic core, we can categorize transformers into two types: Core of Shell Type Transformer We use ‘E’s and ‘L’s shape laminations to make the core of the shell-type transformer. Limb of Shell Type Transformer A single-phase shell type transformer has a core with three limbs, enhancing mechanical strength and … Read more
The connection of several generating stations at a specific transmission voltage level is known as an electrical grid system. By interconnecting different power-generating stations, we can solve various power system challenges. The structure, or “network topology,” of a grid can vary based on load, generation characteristics, budget constraints, and reliability needs. The physical layout is … Read more
A linear amplifier like an op amp has many different applications. It has a high open loop gain, high input impedance and low output impedance. It has high common mode rejection ratio. Due to these favourable characteristics, it is used for different application. In this article, we are discussing some of the most prominent uses … Read more
DC-DC converters are also known as Choppers. Here we will have a look at the Step Up Chopper or Boost converter which increases the input DC voltage to a specified DC output voltage. A typical Boost converter is shown below. The input voltage source connects to an inductor. A solid-state switch is connected across the … Read more
Electrostatic precipitators are essential in thermal power plants and other power plants to reduce flue gas emissions. With growing concerns about environmental pollution, these devices have become a necessity. They use a high-intensity electric field to ionize dust particles in the air stream, which are then collected by oppositely charged electrodes. The collected dust particles … Read more
What is a Power System? An electric power system is defined as a network of electrical components used to supply, transfer, and consume electric power. The supply is done through some form of generation (e.g. a power plant), the transfer is done through a transmission (via a transmission line) and distribution system, and the consumption … Read more
