2024-01-01T09:56:47+00:00

This paper introduces an innovative approach to address the escalating demand for critical medical equipment, particularly ventilators, amid the COVID-19 pandemic. To ensure precision and stability in operation, a direct current (DC) motor is engineered to maintain a constant speed and voltage, irrespective of fluctuations in system load. Given the imperative need for cost-effective and adaptable ventilators in emergency medical applications, the proposed solution stands as a pivotal contribution. In response to the urgency of the situation, this research leverages fuzzy logic techniques, implemented using Matlab, to create a sophisticated control system for the DC motor. Fuzzy rules are replicated in Matlab, enabling the system to dynamically adapt to changing conditions and demands. The utilization of fuzzy logic controllers is a key highlight, facilitating efficient speed and voltage control of the DC motor. This control mechanism operates through a judicious combination of field current and armature voltage in the constant power region while relying on armature voltage in the constant torque zone. This approach not only enhances the adaptability of the ventilator system but also contributes to its affordability, making it a viable solution for the challenging landscape of emergency medical scenarios.

Our reliance on fossil fuels could be decreased and the energy industry could undergo a revolution thanks to solar power. The incorporation of solar energy into traditional power systems is not without its difficulties, though. Planning, funding, and cooperation will be necessary to overcome these obstacles and make solar energy a substantial part of our energy mix. It's time to start using solar energy and work towards a more sustainable and environmentally friendly future. The energy landscape has changed significantly as solar power becomes more and more integrated into conventional power systems. Positive effects include a drop in electricity prices, a diversification of energy sources, and a reduction in carbon emissions. But it also presents problems, such as the requirement for upgrades to the grid's infrastructure and intermittency. It is anticipated that as solar technology continues to progress and smart grid solutions are developed, the amount of solar power integrated into conventional power systems will increase and contribute to a more sustainable and dependable energy future. While there are many advantages to solar power plants, there are drawbacks as well, such as problems with power quality and harmonic generation. It is crucial to deal with these problems early on since they may affect the plant's dependability and efficiency. Solar power plants can reduce the effects of harmonics and power quality problems with appropriate design, operation, and maintenance, guaranteeing a more dependable and sustainable supply of renewable energy in the future.

This system proposes the utilization of a brushless DC (BLDC) motor drive to power a water pump system fed by a solar photovoltaic (PV) array. The aim is to offer a solution that is user-friendly, cost-effective, and energy-efficient. A DC-DC motor is used to harvest the power that is available from the SPV array on the outside. By getting rid of phase current identifiers and changing over the Z Source Inverter (ZSI) to an abecedarian recurrence, the proposed control calculation forestalls power misfortunes welcomed on by high-recurrence exchanging. The speed of the BLDC engine can be overseen without the necessity of extra equipment or control frameworks by using the ZSI's flexible DC interface voltage considers speed guidelines. Furthermore, the soft starting of the BLDC motor is achieved through effective control of the DC-DC converter using the Incremental Conductance Maximum Power Point Tracking (INC-MPPT) technique. The recommended water siphon framework is displayed and created in a manner that guarantees execution under powerful settings. The adequacy of the proposed framework under true working circumstances is shown by MATLAB/Simulink reproduction results that are accordingly affirmed by tests.

Improved Voltage Boost Converter Utilising SEPIC Configuration for Renewable Energy Implementation

2024-04-23T05:08:35+00:00

This paper introduces a novel high-step-up DC-DC Converter that utilizes the Single-Ended Primary Inductor Converter (SEPIC) configuration, representing a significant advancement in the realm of power electronics. The proposed converter aims to achieve notably higher voltage output compared to conventional converters, thereby enhancing overall power conversion efficiency and reducing component stress. This idea introduces two high static gain step-up DC-DC converters derived from a customized version of the SEPIC converter. These proposed configurations are especially advantageous for applications necessitating efficient conversion from low input voltage to high output voltage, due to their optimized switch voltage and superior overall efficiency. The paper comprehensively examines and presents both magnetic coupling and non-magnetic coupling configurations. The increase in static gain is facilitated by the magnetic coupling, which helps keep the switch voltage low. Theoretical evaluations and experimental results demonstrate the suitability of both designs for applications demanding high static gain, particularly in renewable energy and low DC output voltage power sources.
