Introduction of power electronics

Introduction of power electronics

  • Power electronics belongs partly to power engineers and partly to electronics engineers. It means it is the combination of power engineering and electronics engineering.
  • Power engineering is mainly concerned with generation, transmission, distribution and utilization of electric energy at high efficiency.
  • The simple engineering is guided by distortion-less production, transmission and reception of data and signals of very low power level of the order of a few watts, or milliwatts without much consideration of the efficiency.
  • Power electronics is also known as industrial electronics.
  • The apparatus associated with power engineering is based mainly on electromagnetic principles, whereas in electronics engineering they are based on physical phenomenon in vacuum, gases/vapours and semiconductors.
  • This subject concerns the application of electronic-principles into situations that are rated at power levels rather than signal levels.
  • It may also be defined as a subject that deals with the apparatus and equipment working on the principle of electronics, but rated at power level, not at signal level.

Constraints | Classification and Properties of constraints | Classical mechanics

Constraints and its classification Constraints force Constraints are restrictions that limit the motion of the particles of a system. Physically constrained motion is realized by the forces which arise when the object in motion is in contact with the constraining surfaces or curves. These forces are called constraint forces. Properties of constraints force They are elastic in nature and appear at the surface of contact. They are so strong that they barely allow the body under consideration to deviate even slightly from a prescribed path or surface. This prescribed path or surface is called a constraint. The effect of constraint force is to keep the constraint relations satisfied. Classification of constraints           Scleronomic and Rheonomic This classification is based on time. The constraints are said to be scleronomic constraints, if the constraint relations do not explicitly depend on time. But if the constraint rela...
