It is used by railways all over the world, and it has a proven track record of safety and performance. Here is a table that summarizes the advantages of … Read more
Wave trap, also known as line trap, are passive filters that block high-frequency signals from entering power lines. They are typically used in substation entrances and exits to protect sensitive equipment from interference and to prevent high-frequency signals from propagating onto the power grid. Working Principle Wave traps work by using a resonant circuit to … Read more
Active power is the real power that does useful work in an electrical circuit. It is the power that is used to light bulbs, run motors, and power other devices. Active power is measured in watts (W). Reactive power is the power that flows back and forth between the source and load in an electrical … Read more
A single-phase full bridge inverter is a type of power electronic circuit that converts direct current (DC) power to alternating current (AC) power. It is one of the most common and versatile inverter topologies, and it is used in a wide variety of applications, including motor control, power supplies, Circuit Diagram The circuit diagram of … Read more
A silicon controlled rectifier (SCR), also known as a thyristor, is a four-layer semiconductor device that acts as a highly controllable switch. It can be turned on or off by applying a small voltage to its gate terminal. When it is turned on, it allows current to flow in one direction, but not the other. … Read more
An LVDT, or Linear Variable Differential Transformer, is a type of transducer that converts linear displacement, the movement of an object along a straight line, into an electrical signal. This signal, typically a voltage or current, is proportional to the displacement of the object, making LVDTs highly accurate and reliable displacement measurement devices. Working Principle … Read more
Thyristors, also known as silicon-controlled rectifiers (SCRs), are crucial semiconductor devices widely used in power electronics applications due to their ability to control large amounts of current with minimal power loss. To effectively utilize thyristors, it is essential to understand the critical parameters governing their operation, including latching current and holding current. Defining Latching Current … Read more
Air conditioners have become an essential appliance in many households, providing much-needed relief during hot and humid weather. However, their operation can also contribute significantly to household energy consumption. Understanding the power consumption of your AC unit can help you make informed decisions about its usage and potentially reduce your electricity bills. Understanding Cooling Capacity … Read more
A transducer is a device that converts energy from one form to another. In other words, it takes one kind of energy, like sound or light, and changes it into another kind of energy, like an electrical signal. Transducers are used in many different applications, including microphones, loudspeakers, thermometers, and pressure sensors. There are two … Read more
