The vigorous growth of electric vehicles in the field of automobile paves the way for the development of dc-dc converter. A novel high gain super Luo dc-dc converter is proposed in this article. A modification is suggested in the topology when the converters are cascaded for high gain. This suggested modification can be applied to any topology for reliable capacitor. The presented converter adds boosting (voltage multiplier) cell before the load to expand the voltage conversion ratio. This converter renders remarkable features like extended voltage gain, low voltage stress on power switches, minimal capacitor stress and less component count. The operating principle and steady-state analysis of the proposed topology is presented. The main feature of the proposed topology is reduced capacitor stress which is evaluated by reliability study with military handbook MIL-HDBK-217F. The significance of minimal capacitor stress with the failure of the capacitor is elaborated. Simulation on the derived topology is carried out with Matlab/Simulink and it validates the theoretical results. Furthermore, the proposed topology is extended with dual output which makes the restructured converter suitable for Electric vehicle application and the simulation of the dual output topology is performed and studied. The experimental results obtained from the 50 W prototype validate the complete steady-state analysis performed on the proposed topology.

Multi-port converters have fewer components count and less conversion stage than the traditional power processing solution which adopts several independent two-port converters. This paper emphasis on the use of a single power processing stage to interface multiple power inputs integrates power conversion for a hybrid power source. The classification of various multiport dc-dc converters topologies both isolated and non isolated are studied and the features are listed.

This article focuses on the performance assessment of a grid-connected 140-kW photovoltaic (PV) plant which is installed on the roof of an aerospace hanger block located at the SRM Institute of Science and Technology, Kattankulathur, Tamil Nadu, India. The installed unit comprises of seven parallel strings, each comprised of 60 modules. Each of the seven strings is separately connected to an individual inverter (Delta RPI-M20A), i.e., a string inverter of 20 kW. An investigation deals with parameters recorded based on the average of daily, monthly, and yearly data such as AC and DC energy generated, reference yield, array yield and final yields, performance ratio and capacity factor. In the year 2020, the total power generated by the proposed project site is 139,125 kW. Further, the average reference yield varied from a minimum of 118.9 (hr/mth) to a maximum of 197.6 (hr/mth). Similarly, the average final yield varies from 86.14 (hr) to 135.61 (hr). The capacity factor and performance ratio are found to have a maximum of 18.83% and 80.29% and a minimum of 11.96% and 64.14%, respectively. Thus, this article helps readers identify the practicability and sustainability of solar-powered PV systems in rural and remote locations.

In recent years, industries in the suburb have retrofitted their power supply units with solar power supply systems. Using solar power supply systems for various applications, such as food processing, enables energy expense saving. A promising opportunity in the food industry is solar-powered Pulsed Electric Field (PEF) used in the treatment of fruits and their by-products. For this application, a converter is proposed in this paper with a combination of a passive switched inductor cell and a switched capacitor cell. Furthermore, the derived topology possesses an extendable feature. This topology generates high voltage repetitive pulses with a single semiconductor switch and a reduced component count. Dynamic study of the converter is also performed with the derivation of the transfer function. Cost effective, reliable, and simple circuitry are the critical features of this topology. The circuit topology can generate high voltage pulses by increasing the number of switched inductors and switched capacitor cells. A correlation study on the impact of the switched inductor/capacitor cell is also performed and analyzed, which is not usually performed. A 50 W prototype is designed and tested to validate the performance of the converter
