How Transformers Work

Definition: According to definition given in Wikipedia an electrical transformer is a stationary equipment that exchanges electrical power across a couple of closely wound coils. A constantly altering current in one winding of the transformer generates a varying magnetic flux, which, consequently, induces a varying electromotive force over a second coil built over the same … Read moreHow Transformers Work

Understanding MOSFET Turn-ON Process

While designing MOSFET based circuits you might have wondered what is the correct way of turning ON a MOSFET? Or simply what is the minimum voltage that should be applied across gate/source of the device to switch it ON perfectly? Although for many digital systems this might not be an issue, 5V systems such as … Read moreUnderstanding MOSFET Turn-ON Process

Capacitor Inductor Calculations

Inductors can be imagined as the opposite of capacitors. The main difference between a capacitor and an inductor is that a capacitor carries a protective dielectric between its plates, which inhibits the conduction of current across its terminals. Here it acts like an open circuit. On the other hand the inductance of an inductor is … Read moreCapacitor Inductor Calculations

Understanding Scalar (V/f) Control for Induction Motors

induction rotor

In this article we will try to understand how scalar control algorithm is implemented for controlling induction motor speed with relatively straightforward calculations, and yet achieve a reasonably good linearly variable speed control of the motor. Reports from many top market analysis reveal that induction motors are the most popular when it comes to handling … Read moreUnderstanding Scalar (V/f) Control for Induction Motors
