Abstract

This work proposes a three-leg asymmetrical voltage resonant converter for multiple load Light Emitting Diode (LED) lighting applications. The proposed converter is developed with a common leg-1 for both load-1 and load-2. The load-1 is powered from asymmetrical voltage between leg-1 and leg-2. Similarly, load-2 is powered from asymmetrical voltage between leg-1 and leg-3. The proposed circuit provides the following major contributions: (1) Independent dimming control of LED loads; (2) Zero Voltage Switching (ZVS) of all power switches; (3) High efficiency; and (4) Asymmetrical voltage regulation. To achieve independent dimming control, the voltages between legs are made zero by dimming leg-2 and leg-3 independently. Two resonant circuits are connected in the proposed circuit. Owing to this all the power switches operate with ZVS, which reduces the switching losses. Further, two LED lamps are connected in series with battery sources to supply the threshold voltage to lamps which in turn results in a lower power processing of the converter.

Practical and Social Implementation of Research

To achieve effective and efficient use of energy resources under the sustainable development goals, Light Emitting Diodes (LEDs) have emerged as a global lighting industry solution. Over the conventional lighting sources such as incandescent lamps, fluorescent lamps, and high intensity discharge lamps, LEDs are i) more efficient, ii) eco-friendly due to absence of toxic gases, iii) have longer life span up to one lakh year, iv) high luminous intensity and v) good colour rendering index. LED’s requires low voltage direct current supply and the V-I characteristics of LEDs which is like Shockley diode represents the exponential growth of current over a small voltage variation which may damage the LED or effects the illumination. Hence, an LED driver is necessary in an LED system to supply LEDs with constant current. DC fed LED drivers are more reliable due to absence of AC-DC conversion stage and power factor correction stage which are crucial in AC fed LED drivers. Therefore, DC fed LED drivers are paid more attention in recent times in the majority of battery-powered/solar-powered applications. Given its features of high power, exceptional efficiency, cost-effectiveness, and flicker-free operation, this innovation is well-suited for streetlight/stadium lighting applications.

Electric Vehicles are in vogue today, thanks to the heightened environmental concerns, greater availability of models, increased cost competitiveness and improved vehicle ranges. To contribute to the growing field of electric vehicle technology, Assistant Professors, Dr Tarkeshwar Mahto, Dr Somesh Vinayak Tewari and Dr Ramanjaneya Reddy from the Department of Electrical and Electronics Engineering at SRM University-AP along with the research scholar, Ms K Mounika Nagabushanam, conducted a study and published a research paper titled “Development of High-Gain Switched-Capacitor Based Bi-Directional Converter for Electric Vehicle Applications.” The team’s research focuses on creating a bi-directional DC-DC converter that enables power flow from the battery to the motor and vice versa while maintaining necessary voltage gains and ensuring improved efficiency and low cost.

Abstract

High efficiency, high voltage transfer ratio (VTR), and low input ripple current are required in any bidirectional DC-DC converter (BDC) that plays a major role in interfacing batteries in applications like DC microgrids and electric vehicles (EVs). To meet these requirements, a switched capacitor-based BDC is proposed to interface the battery with a propulsion system via a DC Link. It has a simple circuit with only a set of switching operations, High VTR, and lesser ripple current on the low voltage (LV) side, which are advantages of the proposed High Gain Switched-Capacitor Bi-directional DC-DC Converter (SC-BDC), making it appropriate for use in EVs. The steady-state analysis, design consideration of passive components, loss and efficiency analysis are presented. Finally, the proposed High Gain SC-BDC is compared with a few of the existing BDCs in the literature. The feasibility of the converter was demonstrated by simulating a 200 W converter and validating results produced in a MATLAB environment.

Explanation of the Research in Layperson’s Terms

Bombay/Mumbai is a great city widely celebrated in literature, especially for its cosmopolitanism. Salman Rushdie’s novel The Moor’s Last Sigh has been read by various critics for the richness of the portrayal of Mumbai. In their research, PhD scholar Jintu Alias and her PhD supervisor Dr Soni Wadhwa have analysed the representation of Cochin in the novel. Regarding their research they say, “For very long, Cochin’s presence has been eclipsed by that of Mumbai. But there is more to the novel than Bombay’s history. Like any art or literature, this novel is open to multiple interpretations. Our study is focused on the depiction of space in postcolonial literature with a focus on the island city Cochin in Kerala. When we immersed ourselves into the novel, we found that its charm is irresistible. Rushdie primarily opened a new city for other writers to explore. This novel was followed by several more novels that took an even closer look at the history of Cochin (now Kochi).”

Abstract

Indian fiction and critical engagements with it have a metropolitan bias. The preference for representations of big cities such as Mumbai in fiction means that non-metropolitan (“provincial”) spaces in India face neglect, literary and otherwise. This article argues for provincialising Indian fiction by exploring non-metropolitan locations as imagined in works of fiction to unpack alternative spatiality. The example offered is Salman Rushdie’s The Moor’s Last Sigh. In most readings of the novel, Bombay (along with Moorish Spain) is highlighted as a metropolitan model for India. Cochin does not figure in these readings, which are passed over as if just a random background or setting for the characters to be launched into Mumbai. This article addresses Cochin’s marginalisation by investigating how the island city offers a provincial, alternative, non-metropolitan theorisation of spatialities in Indian fiction. The larger objective is to make space for similarly marginalised non-European locales in the discourse of cosmopolitanism.

Social Implications

  1. We hope that with this interpretation of the novel from the point of view of Cochin and its history and cosmopolitanism, smaller cities in India get more attention from literary critics.
  2. We also hope that our research excites further studies and creative writing on other aspects of cultural traditions practised in smaller cities in India. There are many more themes and historical and geographical settings to explore in Indian literature!

Future Research

In continuation of our method of reading different Kochi texts, we will engage with more novels in the future. Our previous reading of another Kochi novel was published in Modern Jewish Studies in September 2023. We look forward to strengthening this body of work in the future.

About This Collaboration

PhD scholar Ms Jintu Alias and Assistant Professor Dr Soni Wadhwa have been working on this area of the Kochi novel since May 2021. This has been an exciting spatiality project in the context of Indian literature.
