Multiple Input Bidirectional DC–DC Converter for DC Drive Applications
Abstract: Multiple input bidirectional DC–DC converter is presented in this paper. This converter is used as an auxiliary supply for a DC motor drive. Motoring action as well as regenerative braking take place due to the bidirectional power flow capability of the converter. The converter is more advantageous because of multiple input capability. This will reduce the components and so the size of the overall system. Moreover the converter can interface …

Renewable Energy using Smart Grid Embedded System in an Internet of Thing
Abstract: The customer domain of the smart grid naturally blends with smart home and smart building systems, but typical proposed approaches are “distributor-centric” rather than “customer-centric,” undermining user acceptance, and are often sparingly scalable. To solve this problem, we propose a detailed architecture and an implementation of a “last-meter” smart grid the portion of the smart grid on customer premises embedded in an internet-of-things (IoT) platform. Our system determines both the …

Electrical Characteristics of a Solar Cell/PV Module
Abstract: Conventionally, a PV system consists of solar PV arrays and electric converters. A PV array is formed by series/parallel combination of solar modules. Some operating conditions result in non-uniform irradiance of PV array, such as shadows, clouds, dirt, debris, bird droppings, different orientations and tilts, and so on. If several solar cells in a series PV module are mismatched due to non-uniform irradiance, these cells will limit the output current …

Design and Analysis of Multiband RMPA at Lowest Frequencies With Miniaturization in Its Dimensions
Abstract: In this paper, two different designs of compact microstrip patch antennas are proposed. The central goal of these proposed designs is to miniaturization of the overall size of the antennas and making them resonant at lowest possible frequencies simultaneously. The first design is the dual band compact rectangular microstrip patch antenna resonant at 0.56 and 2.4 GHz. In this design, the compactness is achieved by using DGS and defected patch …
