This paper is about the simulation study of auxiliary converters used in 6000 HP electric locomotives used in India. Simulation is a mirror of the operation of a real-world method or system. The process of simulating a system first requires that a model be designed. This model represents the key behaviors, characteristics, and functions of the selected physical or abstract system. It helps to analyze the behavior of the system without even building it. The results obtained are accurate in general when compared to the analytical model. It also helps to find unexpected errors and behavior of the system. Simulation is easy to perform “What-If” analysis. For this purpose, MATLAB/Simulink was used.

This paper proposes an “arrangement of converters for the incorporation of a huge photovoltaic (PV) plant with an utility AC lattice. “The framework involves a focal seven-level voltage-bolstered inverter (VFI) and a substantial number of PV modules with module-incorporated DC-DC converter. The seven-level VFI comprises of three-stage, three-level VFI units associated in parallel on the AC-side. This paper additionally proposes another sun based power age framework, which is made out of a DC/DC and DC/AC control converter and another seven-level inverter”. This new seven-level inverter is arranged utilizing a capacitor choice circuit and a full-connect control converter, associated in course. Seven dimension changes over sustained with PV modules give a practical answer for moderating consonant related issues brought about by diode or thyristor rectifier front-closes. To deal with the huge remuneration flows and give better warm administration, at least two paralleled semiconductor exchanging gadgets can be utilized. The proposed PV based seven dimension topology can likewise create seven voltage levels, which fundamentally diminishes the exchanging current swell and the measure of inactive components.The execution of the proposed power converters framework is considered utilizing MATLAB/Simulink.

The energy efficiency requirements of most energy-consuming sectors have increased recently in response to climate change. For buildings, this means targeting both facility managers and building users with the aim of identifying potential energy savings and encouraging more energy-responsible behaviors. The Information and Communication Technology (ICT) platform developed in Horizon 2020 FEEdBACk project intends to fulfill these goals by enabling the optimization of energy consumption, generation, and storage and control of flexible devices without compromising comfort levels and indoor air quality parameters. This work aims to demonstrate the real-world implementation and functionality of the ICT platform composed of Load Disaggregation, Net Load Forecast, Occupancy Forecast, Automation Manager, and Behavior Predictor applications. Particularly, the results obtained by individual applications during the test phase are presented alongside the specific metrics used to evaluate their performance.

This paper presents the design and control of a magnetically suspended ceiling actuator which combines four iron-cored linear actuators and a checkerboard permanent magnet array for an infinite planar stroke. When the actuators are rotated with respect to the PM array, it is shown that the thrust and normal force produced by the three-phase linear actuators can be controlled by applying Park's transformation. The design of the iron-cored linear actuators is optimized for minimum losses when the translator inside the ceiling actuator and a payload are accelerated in the xy-plane. The optimization is performed using an analytical model is. Simulations of the optimized design with a 3D FE-model, show a maximum tracking error of 1 μm and rotations of 30 μrad when the translator is moved and controlled in 6 DOF.
