1. Introduction: Bridging the Gap in Modern Engineering
In an era defined by the rapid electrification of transport and the volatile integration of renewable energy, the complexity of modern electrical systems has reached an unprecedented peak. To navigate this landscape, the curriculum for the next generation of engineers must be architected to bridge the chasm between abstract mathematical modeling and physical implementation. Addressing this critical need, the Department of Electrical and Electronics Engineering at Assam Don Bosco University (ADBU), in prestigious partnership with the Department of Electronics and Electrical Engineering at IIT Guwahati, hosted a Two-Day “Technical Workshop on Power Electronics” on March 13–14, 2026. Supported by the Anusandhan National Research Foundation (ANRF) under the Scientific Social Responsibility (SSR) initiative - a flagship program of the Department of Science & Technology, Ministry of Science & Technology (Government of India), the event drew approximately 100 attendees, including faculty and a diverse student cohort that featured an interdisciplinary draw of four students from the Department of Electronics and Communication Engineering (ECE). Led by Dr. Chandan Kumar, Associate Professor at IIT Guwahati, the workshop transformed the ADBU Azara campus into a hub of high-level topological analysis and iterative verification.
2. A Deep Dive: The Two-Day Curriculum
The workshop was structured to move systematically from the abstract to the concrete, ensuring that participants developed a holistic understanding of power electronic systems through the following technical milestones:
Day 1: Foundations and Simulation
- Theoretical Framework: Introduction to the core significance of power electronics in global infrastructure.
- Systemic Applications: Exploration of the role of converters in electric vehicles (EVs), renewable energy grids, and advanced battery management.
- Topological Analysis: Detailed examination of switching devices and various power converter topologies.
- The Buck Converter Focus: In-depth analysis of DC–DC step-down conversion, emphasizing key derivations and operating principles.
- Computational Modeling: Utilizing simulation tools to demonstrate the precise relationship between switching operation, duty cycle, and output voltage.
Day 2: From Schematic to Hardware
- System Design: Introduction to the architecture and testing of a regulated DC power supply circuit.
- Component Identification: Hands-on identification of critical hardware, including step-down transformers, bridge rectifiers, filter capacitors, and voltage regulators.
- Thermal and Physical Discipline: Practical training in precision soldering and the rigorous verification of circuit connections.
- Polarity and Verification: Meticulous checking of electrolytic capacitors and diodes to prevent circuit failure.
- Output Measurement: Utilizing the multimeter as the ultimate arbiter to verify regulated rails across +/- 5V, +/- 9V, and +/- 15V outputs.
3. Takeaway 1: The Simulation-to-Reality Pipeline
Modern power engineering demands a "simulation-first" mindset. By focusing on the buck converter—a ubiquitous component in the voltage regulation of consumer gadgets and industrial controllers—participants engaged with the key derivations that govern switching performance. This phase was not merely a precursor to assembly but a necessary analytical step to observe how micro-adjustments in the duty cycle dictate the macro-behavior of the output voltage.
"...illustrating how theoretical concepts can be implemented and analyzed using simulation tools."
This digital sandbox allows for the safe exploration of converter operation, ensuring that when students finally handle physical components, they do so with a predictive understanding of the system's behavior.
4. Takeaway 2: Power Electronics as the Green Energy Enabler
A recurring theme throughout Dr. Kumar’s sessions was the realization that power electronics serves as the invisible backbone of the global green energy transition. Efficient power conversion technologies have evolved from niche circuit design problems into a global necessity for sustainability. Whether managing the delicate charging cycles of an EV battery or stabilizing the output of a wind turbine, the buck converter and its topological relatives are the primary tools for energy efficiency.
"Power electronic converters play a growing role in various applications such as electric vehicles, renewable energy systems, and battery management, making them vital to modern electrical and electronic systems."
Participants analyzed how these systems are not merely components but integrated solutions that allow sustainable technology to interface reliably with the existing power grid.
5. Takeaway 3: The Discipline of Hardware Implementation
The transition to hardware in the workshop venue revealed the visceral complexity of turning a schematic into a functional power board. The conversion from AC input to a stable, regulated DC output is a fundamental challenge that tests a student's technical discipline.
Identifying the correct polarity for electrolytic capacitors and diodes became a high-stakes exercise in precision. A single orientation error in a bridge rectifier circuit can lead to catastrophic failure, a reality that emphasizes the "measure twice, solder once" philosophy of professional engineering.
The process of generating multiple regulated outputs (+/- 5V, +/- 9V, and +/- 15V) provided a practical lesson in supporting embedded systems. Success was not found in the assembly alone but in the iterative process of "expected vs. measured" recording.
Through the assistance of IIT Guwahati research scholars, participants learned that hardware success is the product of meticulous troubleshooting. Using a multimeter to verify each rail proved that in power electronics, the difference between a functional tool and a failed experiment lies in the details of the connection.
6. Conclusion: The Future of Power Conversion
The collaboration between IIT Guwahati and ADBU successfully integrated the three pillars of technical education: theory, simulation, and hardware implementation. By moving from the mathematical foundations of switching devices to the physical measurement of regulated DC outputs, the workshop provided a comprehensive roadmap for the next generation of engineers. As we face an increasingly electrified future, the ability to navigate both the digital simulation and the physical hardware will remain a defining skill for those tackling the world's most pressing energy challenges.
