Power Electronics

covers how power semiconductor devices and converters shape and control electrical power, from rectifiers through choppers to inverters, the switching technology behind motor drives, renewable interfaces and power supplies.

Digital Circuits

builds combinational and sequential digital logic design skills, from Boolean minimization through counters and registers to digital IC families, feeding directly into the microprocessor and embedded-systems work later in the program.

Power Systems-II

covers how transmission line parameters, performance and transients are calculated and designed, the analytical backbone for planning and operating the transmission network.

Professional Elective-I: Signals and Systems

introduces the mathematical language of signal classification, transforms and system properties used to analyse how electrical systems respond to different inputs.

Professional Elective-I: Computer Architecture and Organization

explains how a digital computer is organized internally (registers, control units, pipelining, memory and I/O), background knowledge that supports the microprocessor and embedded-systems work ahead.

Professional Elective-I: Communication Systems

surveys how information is modulated, transmitted and coded across analog and digital communication systems, from AM/FM principles to modern mobile and satellite links.

Open Elective-I: Renewable Energy Sources

surveys the major renewable energy technologies (solar, wind, biomass, ocean and chemical sources) that electrical engineers increasingly need to integrate into the grid.

Open Elective-I: Concepts of Energy Auditing & Management

covers how to audit and manage industrial and building energy use, from basic audit principles through efficient motors and power-factor correction to the economics of energy-saving investments.

Entrepreneurship Development & Venture Creation

listed in the course structure as an alternative to Open Elective-I, but the source syllabus PDF does not contain a unit-wise syllabus for this course anywhere in its 186 pages, so no unit breakdown can be given honestly here.

Power Electronics Lab

hands-on experiments that verify the device characteristics and converter behaviour covered in the Power Electronics course, from firing circuits to inverter control.

Analog and Digital Circuits Lab

combines analog circuit experiments (clippers, oscillators, op-amp applications) with digital circuit realization (adders, counters, registers) to reinforce both electronics courses on the bench.

Soft Skills

a skill-enhancement course on communication, self-management and interview readiness aimed at making engineering graduates workplace-ready beyond their technical training.

Tinkering Lab

a hands-on prototyping lab where students build small electronics and IoT projects to develop practical problem-solving and innovation skills that complement classroom theory.

Evaluation of Community Service Internship

the course structure lists this as a 2-credit internship evaluation component with no lecture hours; the source PDF does not provide a unit-wise syllabus for it since it is assessed on the student’s actual internship placement rather than classroom content.
