What is a Proportional Controller?

What is a Proportional Controller? Proportional controller is one of the most basic control algorithms in automatic control systems, usually represented by the letter "P". The proportional controller controls the response of the system by adjusting the output signal to be proportional to the error s

Types of Controllers

Controller Definition In control systems, a controller is a mechanism that seeks to minimize the difference between the actual value of a system (i.e. the process variable) and the desired value of the system (i.e. the setpoint). Controllers are a fundamental part of control engineering and used in

Energy Loss Of Transformers

Losses in Transformer As the electrical transformer is a static device, mechanical loss in transformer normally does not come into picture. We generally consider only electrical losses in transformer. Loss in any machine is broadly defined as difference between input power and output power. When inp

Impedance of Transformer

Leakage Reactance Definition In a transformer, not all the flux links both the primary and secondary windings. Some flux links with only one winding, called leakage flux. This leakage flux causes self-reactance in the affected winding. This self-reactance is also known as leakage reactance. When com

Eddy Current Theory and Applications

Eddy Current Definition According to Lenz’s law, when a conducting loop is exposed to a changing magnetic field, it generates an emf that induces a current opposing the change. Similarly, when a magnetic field changes through a conducting body, like a filament or a slab, it causes currents to flow t
