Introduction to Power Electronics

Hello and wellcome.

              Today i am going to sharing something about Power Electronics. Power electronics is a combination of two engineering field power engineering and electronics engineering. In power engineering, the equipments and apparatus are rated at high power level and high efficiency. In electronics engineering, all the apparatus are rated at signal level without much consideration of efficiency. Power engineering covers the transmission, generation, distribution and utilization of electrical energy. Transmission and reception of data, distortionless production signals of very low power level comes in electronics engineering. Hence the apparatus of power electronics are rated at power level but work on the principle of electronics.

                The electronics power conversion circuit use power semiconductor devices and these circuits convert and control electrical power. These devices operate in the switching mode, which causes the losses to be reduced and therefore the conversion efficiency is to be improved. The disadvantages of switching mode operation are the generation of harmonics. Now a days, the technology is advancing and apparatus cost is decreasing along with the improvement of reliability. Therefore the applicant of power electronics devices are expanding in industrial, commercial, residential, military, aerospace and utility environments.These progress in power electronics is due to advances in power semiconductor devices.

Armature Voltage Control Method or Rheostatic Control of dc motor

Speed Control of D.C. Shunt Motor (Part2)  2. Armature Voltage Control Method or Rheostatic Control        The speed is directly proportional to the voltage applied across the armature. As the supply voltage is normally constant, the voltage across the armature can be controlled by adding a variable resistance in series with the armature as shown in the Fig. 1. Fig. 1 Rheostat control of shunt motor        The field winding is excited by the normal voltage hence I sh is rated and constant in this method. Initially the reheostat position is minimum and rated voltage gets applied across the armature. So speed is also rated. For a given load, armature current is fixed. So when extra resistance is added in the armature circuit, I a remains same and there is voltage drop across the resistance added ( I a R). Hence voltage across the armature decreases, decreasing the speed below normal value. By varyi...

Demagnetising and Cross Magnetizing Conductors

The conductors which are responsible for producing demagnetizing and distortion effects are shown in the Fig.1. Fig. 1        The brushes are lying along the new position of MNA which is at angle θ  from GNA. The conductors in the region AOC = BOD = 2θ  at the top and bottom of the armature are carrying current in such a direction as to send the flux in armature from right to left. Thus these conductors are in direct opposition to main field and called demagnetizing armature conductors.         The remaining armature conductors which are lying in the region AOD and BOC carry current in such a direction as to send the flux pointing vertically downwards i.e. at right angles to the main field flux. Hence these conductors are called cross magnetizing armature conductors which will cause distortion in main field flux.        These conductors are shown in the Fig. 2 Fig. 2  ...
