The Power of Power Electronics

Demand for electrical and electronics engineers in the field of power electronics is steadily on the rise in India. But what is required of them to befit this industry? Let’s look at the current scenario, including entry-level roles, typical pay-packages, skills expected and much more -- Abhishek Mutha

Current scenario of power electronics for engineers in India
“For a few years, there was not much focus on this field as the need was not felt. But today with so many developments happening, the scenario is changing,” says Nayak.

Sharing his personal experience, he adds, “In a multinational company that I worked for earlier, I was responsible for developing a resource base for both R&D and engineering services catering to global requirements. It was difficult in the beginning to get the resources but in a span of two years we managed to hire and develop over 200 resources, though there were only a few experts in this area.”

In India, as there are very few institutes/universities that offer competitive and valuable undergraduate or graduate programmes in power electronics, there is a scarcity of expert manpower in this field, said Vivek Agarwal, professor, Department of Electrical Engineering, Indian Institute of Technology-Bombay.

Entry-level roles could be in technical areas like design, testing and commissioning. Those with a higher proficiency level could move into the research area”

Usually, power electronics companies with indigenous capabilities belong to the small-scale or medium-scale category and do not have significant R&D activity.

Agarwal adds, “During the last two decades, some of the multinational companies have set up their R&D centres and manufacturing units in India where specialised power electronics systems are designed and developed but the number of such organisations is very small.”

What’s it like for freshers?
There are quite a few companies engaged in power electronics products, especially those in energy sector.

Nayak says, “Entry-level roles could be in technical areas like design, testing and commissioning. Those with a higher proficiency level could move into the research area.”

He adds, “Nanotechnology is also bringing in tremendous opportunity in power semiconductor design.” There are also some activities in automotive OEMs and Tier-1 companies in the areas of electric and hybrid vehicles.

“Currently, due to the scarcity of good power electronics engineers, the need is met by recruiting electronics or electrical engineers. Specialised (postgraduate-level) power electronics engineers are usually absorbed by multinational companies in R&D jobs and get to work on specialised projects,” adds Agarwal. He believes that it is not difficult for a fresher with power electronics background to get into this sector.

On a slightly contradictory note, Garadi says, “It is highly unlikely that undergraduate freshers will be able to directly involve in power electronics design activities. However, smart engineers with a flair for power electronics could get into it.”

“With on-the-job training under the guidance of experienced engineers, freshers would do well by starting off with product testing and gaining experience donning the role of a design engineer,” Garadi adds. Postgraduates in power electronics can plunge into design or debugging of power electronics products.

Typical pay packages
Power electronics field offers highly satisfying pay packages. Since it is a specialised segment, competent engineers enjoy a special status vis-à-vis other hardware engineers.

“In fact, they command a better pay package than mixed-signal board designers. The exact pay package depends on the company recruiting, plus the specific skills that the company is seeking. The starting salary for a postgraduate in power electronics could be around Rs 600,000 a year,” Garadi informs.

“For undergraduates passing out from reputed academic institutes and universities, it is approximately Rs 400,000-700,000 a year. For postgraduate students, it is typically Rs 500,000 to Rs 1,000,000, while those with a PhD are able to draw Rs 900,000-Rs 1,600,000 a year,” adds Agarwal.

Skills required
According to industry experts, applied mathematics will go a long way for a good grasp of power electronics. A good background on linear and non-linear systems will help in understanding the various concepts. Circuit simulation will help in reinforcing theoretical concepts.

Garadi suggests, “A good understanding of the behaviour of magnetics, power FETs and IGBTs is the key to designing and debugging power circuits but, finally, a hands-on approach is the only way to master any topic.”

Nayak adds, “Aspirants must be strong in power semiconductors application engineering in power system, as there are tremendous opportunities and also continuous improvement in design of semiconductors focusing on cost and materials used.”

Participating in industrial seminars, conferences and exhibitions related to power electronics systems and products would help improve one’s knowledge base.

Agarwal says, “An internship in the power electronics division of reputed organisations would help one gain a good experience of designing and fabricating at least some basic power electronics systems.”

Short-term courses to fine-tune skills
When it comes to short-term courses, there are just a few of them. Some institutes offer advanced training in power electronics for graduates, while others offer courses in power devices, motors and motor controls, AC drives, etc. A few institutes also offer certificate courses in power electronics, power supply design and switched-mode supplies.

Garadi shares, “I do not see any short-term course in power electronics doing full justice to the topic. However, there are a lot of master’s programmes in power electronics offered by many premier technical institutes. IITs, these days, are offering integrated B.Tech and M.Tech programmes in power electronics.”

In addition to the industrial sector, power electronics is rapidly gaining momentum in automotive space too with the advent of electric and hybrid vehicles. Power electronics engineers command a better pay package than mixed-signal board designers. The exact pay package depends on the company recruiting plus the specific skills that the company is seeking”

Nayak concedes, “Best learning is achieved through on-the-job training at the industries as they give tremendous opportunities and challenges for harnessing the skills and also application of their basic knowledge leading to product design and solutions.”

Sharing with us how Bosch spends time and effort in training and sharpening skills of new recruits, Garadi says, “Freshers go through intensive training both in generic topics that they are likely to be associated with and specific domain that they get into.”

He adds, “We are continuously improving the training programmes and the content. We are bringing in hands-on training with a few sample design tasks so that the engineers realise and appreciate the challenges and get an idea of the serious nature of engineering.”
