353 Abstract—This paper describes a new and evolving Electrical Power Generation System by integrating simultaneously Solar Energy, Rains Energy, Wind Energy and Lightning Energy as non conventional energy sources. All the natural wastage energies are used for production of Electricity. Thus, the Electrical Power or Electricity is available with a minimum cost and pollution free to anywhere in ...

Ceramic gas sensors used for measuring ambient air quality have features suitable for practical applications such as healthcare and air quality management, but have a major drawback-large power consumption to preheat the sensor for accurate measurements. In this paper; the adaptive preheating duration control (APC) method is proposed to reduce the power consumption of ambient air quality sensor...

Finite-set model predictive controls have been widely used in inverter control because of the flexible target and no need a modulation unit. However, mismatching prediction parameters produces errors, resulting significant decline performance finite-set controls. Aiming at problem parameter mismatch, an extended-state observer was proposed to accurately estimate disturbance system this paper, o...

This paper presents a new topology of uninterruptible power supply (UPS) by using a Z-source inverter, where a symmetrical LC network is employed to couple the main power circuit of an inverter to a battery bank. With this new topology, the proposed UPS can maintain the desired ac output voltage at the significant voltage drop of the battery bank with high efficiency, low harmonics, fast respon...

The Sliding mode control theory is applied to a sinusoidal output voltage boost inverter with linear load. The boost inverter is intended to be used in UPS design, whenever an AC voltage larger than the DC link voltage is needed, with no need of a second power conversion stage. Operation, control strategy, simulation and experimental results are'included in this paper.

The power electronics device which converts DC power to AC power at required output voltage and frequency level is known as inverter. Multilevel inverter as compared to single level inverters has advantages like minimum harmonic distortion, reduced Electromagnetic interference (EMI)/Radio frequency interference (RFI) generation and can operate on several voltage levels. A multi-stage inverter i...
