Plasmons for Energy Conversion

Axion Emission by Magnetic-Field Induced Conversion of Longitudinal Plasmons

Magnetic fields mix axions with photons, allowing for the cyclotron process e → ea by virtue of an intermediate plasmon even if axions do not couple to electrons at tree level. The axion and longitudinal-plasmon dispersion relations always cross for a certain wave-number, leading to a resonant enhancement of this process. Even then, however, it cannot quite compete with the usual nucleon proces...

Multi-Stage DC-AC Converter Based on new DC-DC converter for energy conversion

This paper proposes a multi-stage power generation system suitable for renewable energy sources, which is composed of a DC-DC power converter and a three-phase inverter. The DC-DC power converter is a boost converter to convert the output voltage of the DC source into two voltage sources. The DC-DC converter has two switches operates like a continuous conduction mode. The input current of DC-DC...

Control‌-Strategies-for-Performance-Assessment-of-an- Autonomous Wind Energy Conversion System

Renewable energy sources like wind, sun, and hydro are considered as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. This paper describes modeling and simulations to determine a method for the power performance evaluation of autonomous wind turbine system. A speed control regulator is utilized to control the DC bus voltage. The inverter gate’s signals...

A Fuzzy Controlled PWM Current Source Inverter for Wind Energy Conversion System

In recent years, there has been a fast growth in wind energy conversion system (WECS). There are two general types of wind turbines in WECS: fixed speed wind turbines and varying speed wind turbines.Permanent magnet synchronous generator (PMSG) is one of the most attractive generators for the varying speed turbine WECS.In this paper, a fuzzy controller is proposed to control the current source ...
