Some examples of uses for power electronic systems are DC/DC converters used in many mobile devices, such as cell phones or PDAs, and AC/DC converters in computers and televisions. Large scale power electronics are used to control hundreds of megawatt of power flow across our nation.
How important is power electronics in designing and developing an electronic system?
Power electronics is a branch of electronics that deals with the application of electronic devices and associated components to the conversion, control, and conditioning of electric power. Power electronics has a crucial role in the efficient use of electrical energy and environmental control.
What is the importance of power electronics?
The basic functions of importance for power electronics are (1) power conversion, ac to dc, dc to ac, ac to ac, (2) power conditioning to remove distortion, harmonics, voltage dips and overvoltages, (3) high speed and/or frequent control of electrical parameters such as currents, voltage impedance, and phase angle, and …
What is the weightage of power electronics in GATE exam?
Power Electronics in GATE generally has a weightage of 8 to 10 marks. Whereas in ESE prelims 15 to 20 marks are dedicated to this subject. In stage-2 or Mains of ESE exam, Power Electronics becomes even more important with a weightage of 40 to 70 marks.
How important is power electronics in ESE exam?
In stage-2 or Mains of ESE exam, Power Electronics becomes even more important with a weightage of 40 to 70 marks. Few topics are common to both GATE and ESE exam, whereas three topics are exclusively included for ESE exam only.
What are the applications of power electronics?
Power electronics also finds application in various modern-day technologies like traction, hybrid cars, robotics, aircrafts, X-rays, scanning machines, medical laboratories and also in telecommunication where we use power electronic converters.
Should I study power electronics or electric machines first?
Electric Machines: To get understanding of fundamentals of drives, it is advisable to study Electric Machines before Power electronics. Signals and systems: To analyze wave-forms, a thorough knowledge of Fourier series is necessary.
