Dr. Gourang N Mulay
Get To Know Me
I am currently a senior Professor in the School of Electronics and Communication at MIT World Peace University, Pune, which was earlier known as the Department of Electronics and Telecommunication at Maharashtra Institute of Technology, Pune.
I have wide and varying experience of over 40 years in the Engineering Industry, College and University Teaching and now Industrial Consultancy. After completing my B.Tech (Electrical) and M.Tech (Electrical) in 1977 & 1979, respectively, from the Indian Institute of Technology, Bombay, I joined the Swedish MNC ASEA Ltd, in the Relay Division in Mumbai in August 1979, interacting with various senior electrical engineers from different State Electricity Boards in the country. I then shifted to Advani Oerlikon Ltd, Pune to the Electronics Division in November 1982 and finally to the Research and Development Laboratory of the Professional Electronics Equipment factory of Dutch MNC Philips India Ltd at Pune in May 1983.
The 10 years I spent in Philips India in the development of Analog instrumentation circuits as well as Switched Mode Power Supplies were the most valuable in honing my technical design and development skills in the area of analog electronics and gave me the confidence to design, develop and troubleshoot various Power Electronics modules. A five week intensive training course at the Power Supplies factory of Philips Industrial Electronics at Wavre, Belgium from January 1989 to February 1989 was the culmination of my exposure to the design, development and testing of power supplies techniques followed by renowned multinational corporations.
In July 1993, I changed from industry to teaching, joining the Department of Electronics and Telecommunication at Maharashtra Institute of Technology, Pune (E&TC, MIT Pune) as an Assistant Professor (today's Associate Professor). Within the first few years at MIT, I developed the Power Electronics Laboratory of the department by designing, building and testing different Power Electronics Kits required for the Third Year Power Electronics course as well as the Final Year Advanced Power Electronics course. These included single and three phase controlled rectifiers, inverters, choppers, AC regulators and different DC drives. These kits are still in use today even after 20 years of use by numerous batches of students.
During this period I also completed my Ph.D in Electronics and Telecommunication from Government College of Engineering, Pune affiliated to the University of Pune.
In 2001, I took over as the Head of the E&TC Department and continued till 2016. The highlights of these years was the National Board of Accredidation (NBA) accredidation of the department in 2003, 2008 and then in 2014. Another major milestone was the introduction of the Postgraduate course Master of Engineering in Electronics (Digital Systems) in 2006.
I was also awarded the “Ideal Teacher of Repute Award” by our parent body, Maharashtra Academy of Engineering & Education Research, Pune on 5th Sept. 2005, Teachers Day.
Since 2019, I have taken up Industrial Consultancy in Power Electronics and am slowly building it up.

Current Interests
Power Electronics Projects & Consultancy
a) Developed the Power Electronics laboratory of the Department of E&TC, MIT by designing, building and testing single and three phase controlled rectifiers, inverters, choppers, AC regulators and different DC drives required for the Third Year Power Electronics course and the Final Year Advanced Power Electronics course.
b) Upgraded from analog control to DSP controller based systems using the Texas Instruments C2000 series TMS320F28335 DSP controller to implement a Digital IDMT single phase overcurrent relay for power system protection.
c) Completed a small industry consultancy project “Overvoltage Protection Circuit” for M/s Koustubha Udyog, Pune, under the Defence Equipment Manufacturers Association (DEMA), Pune, group. This involved the prototype development of a Crowbar Overvoltage Protection circuit for preventing damage to 24 V DC operated Electronic Pressure Transmitters in case 230V AC mains supply is inadvertently connected during installation and commissioning.
d) Currently providing consultancy to M/s. Innoplas Technologies Pvt. Ltd, Pune for the development of power supplies for plasma equipment.
ICT in Engineering Education
a) Developed and implemented an innovative application of Moodle Learning Management System for conducting numerical assignments and tests for different Electrical and Electronics subjects taught.
Normally, a common online home assignment is given to the entire class whcih encourages copying. Similarly, online tests are generally of the MCQ (Multiple Choice Question) type with four choices which can lead to guesswork.
To avoid these drawbacks, numerical questions were given for which students had to enter answers after paper calculations. To allow for loss of precision due to students using their calculators with fewer decimal points, a tolerance was specified (2.5%) within which the answer was considered correct.
To discourage copying, every student got separate questions with separate answers. These questions and their answers were automatically generated using a MATLAB program which wrote the data to an MS Excel spreadsheet. Using the Mail Merge feature of MS Word, the Excel data was written to a Word template and finally imported into the Moodle LMS using a mouse-and-keyboard macro recorder.
With this technique, more than a thousand numerical variations were generated for every question, thereby compelling students to solve the numerical problems on their own without being able to copy from others.
To motivate the students to take these assignments seriously, the "Multiple Attempts" feature of Moodle was enabled, with the best of 10 attempts being used for marking.
