Learners enrolled: 656

Power electronics is a vital field of electrical and electronics engineering that deals with the conversion, control, and management of electrical energy using semiconductor devices. Learning power electronics is important for Efficient Energy Conversion. Power electronics enables efficient conversion of electrical energy from one form to another, reducing energy losses in power systems, renewable energy applications, and consumer electronics. It is at the heart of electric vehicle (EV) technology, controlling battery management, motor drives, and charging systems. Advancements in this field improve the efficiency, performance, and range of EVs. Many industrial applications, such as motor drives, robotic systems, and automated machinery, rely on power electronic converters and controllers to ensure precise and efficient operation. Learning power electronics is crucial for anyone interested in energy systems, electric vehicles, automation, and modern technology. As industries continue to evolve, expertise in power electronics will remain essential for innovation and sustainable development.

Course certificate

"The SWAYAM Course Enrolment and learning is free. However, to obtain a certificate, the learner must register and take the proctored exam in person at one of the designated exam centres. The registration URL will be announced by NTA once the registration form becomes available. To receive the certification, you need to complete the online registration form and pay the examination fee. Additional details, including any updates, will be provided upon the publication of the exam registration form. For more information about the exam locations and the terms associated with completing the form, please refer to the form itself."

Grading Policy:

- Internal Assignment Score: This accounts for 30% of the final grade and is calculated based on the average of the best three assignments out of all the assignments given in the course.

- Final Proctored Exam Score: This makes up 70% of the final grade and is derived from the proctored exam score out of 100.

- Final Score: The final score is the sum of the average assignment score and the exam score.

Eligibility for Certification:

- To qualify for a certificate, you must achieve an average assignment score of at least 10 out of 30, and an exam score of at least 30 out of 70. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >=40/100.
