To expose the inner competencies and enhance the quality work on economic human-centric Ideas developed through Design Engineering subjects taught to the students of various engineering disciplines, Design Demo Day (DDD S-2024) was organized by Power Electronics Department on 20th April 2024 with kind permission from Dr I. N. Trivedi, HOD, Power Electronics Department & Principal Dr V. S. Purani. It was coordinated by Prof. A. M. Haque and Prof. N. D. Mehta. Eight Presentation by third-year engineering students were observed by approximately 125 faculties and students of VGEC, Chandkheda. Prof. Naresh Patel from EC Department, VGEC, Chandkheda was invited to share his experience, teach the students the renowned methodology of Design Engineering for State-of-the-art work, and evaluate the design work performed.

A high-level competition was observed during this Demo. Students have benefitted from this event much more and are enthusiastic to perform better soon. A few impressive projects and heart touching are: 

A Showcase Event highlighting the "Smart Street Light Automation (IoT Based)" project and its innovative concepts by a DESIGN ENGINEERING TEAM Aditya Singh Rajput, Bhadouriya Khushi, Swayam Patel, and Kush Jhaveri aimed to demonstrate the potential benefits of implementing smart street lighting solutions in urban environments, emphasizing energy efficiency, cost savings, environmental impact, and improved safety measures.

The attendees had the opportunity to engage with the project, explore the technological components, and gain insights into how IoT-based automation can transform urban lighting infrastructure. Discussions focused on the practical applications, challenges, and prospects of integrating smart street lights into city landscapes.

Through demonstrations, it has fostered a deeper understanding of the project's significance in shaping a smarter, more sustainable urban future. It underscored the importance of collaborative efforts between academia, industry, and government in driving innovation and addressing urban challenges. Overall, the Showcase Event provided a valuable opportunity for knowledge exchange, networking, and collaboration, laying the groundwork for further advancements in smart city initiatives and urban development.

Dhobi Krishna, Gamit Uchit, Aervadiya Hiren, Radadiya Priya & Mudaliar Swetha emphasized farmers' agriculture issues and prepared a Battery-Operated Power Reaper. Recently available power reaper operates with a power engine coupled through a shaft that takes 1.5 to 2 times fuel more for power reaper than normal operation of the tractor. Battery-operated Power Reaper saves fuel costs, and saves the environment from excess smoke and noise at a very nominal price of rechargeable battery. It will be an addition to the advanced agriculture harvesting tools and farmers will benefit from battery-operated power reaper. 

Devendra Vishnoi, Sahil Chaudhary, Somnath Trinath Panda, Bharat Parsaniya and Maan Parmeet Singh unveiled a power electronics trainer, showcasing a significant advancement in practical learning for students. This trainer features key components like a rectifier, buck converter, voltage regulator, and inverter. This combination allows students to explore the fundamentals of AC-DC and DC-AC power conversion, which is essential for various electronic applications.

The power electronics trainer offers a unique platform for students to gain practical insights into the operation of rectifiers, understanding AC to DC conversion and its impact on output voltage quality. Explore buck converters, delving into the principles of Pulse Width Modulation (PWM) for regulating DC output voltage. Investigate the role of voltage regulators in maintaining consistent voltage levels, crucial for powering sensitive electronic components. Understanding the process of inverting DC voltage back into AC voltage is a fundamental concept for applications like solar power integration into the grid.

By combining these core functionalities in a single platform, the power electronics trainer offers a holistic learning experience. This allows users to not only grasp the individual principles but also understand how these components work together in practical power conversion systems.

This innovative trainer fosters a deeper understanding of power electronics principles, preparing students for real-world engineering challenges. By enabling experimentation and validation of theoretical concepts, the trainer bridges the gap between theory and practice.

There were also projects demonstrated like a lithium-ion battery charger, inverter, Maximum Power Point Tracker Controller for Solar Energy,Pure Sine Wave Inverter System for Air Conditioning, Linear Power Supply and Variable Power Supply.

We emphasized ‘Case Study Report’ and ‘Prior Art Search’ to third-year students & ‘Reverse Engineering’ and ‘Literature Study’ to second-year students. They are keen to work on the design engineering methodology and we expect a few of them will come ahead with innovative marketable economic & socio-centric projects soon.
