Today, the use of renewable energy sources is increasing. Photovoltaic systems are also among sources. These a direct current source and cannot produce when there no sunlight. In this study, performance analysis Hard Switching (HS) DC-DC boost converter Soft (SS) in literature with PID controller were performed on photovoltaic system. The converters, which simulated Matlab/Simulink software was...

In this paper, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...

Renewable energy resources are gaining popularity now a days. Their input varies with changes in climatic conditions. So the output from them is not a constant value. The output of the energy sources have to be connected to grid. But the grid voltage is always constant. So the output from the renewable energy converters have to be constant. But the input of the renewable energy converters alway...

This work presents power generation using Attic type (internally braced) air exhauster to generate the electrical power for industrial application. Generally power can be generated from renewable and non-renewable energy sources like solar, wind, tidal, geothermal, coal, natural gas and petroleum. To satisfy the growing power demand the industry focuses on alternate energy sources like wind dri...

Wind energy, among all of the renewable energy sources, has made rapid developments and significant inroads in electrical power systems. With the increased use of wind energy conversion systems (WECSs), several technologies have been developed. Since WECSs are more cost competitive, the comparison of different wind generator systems is the need of the hour. Permanent magnet generators employing...

Problem statement: A half-bridge LLC resonant converter with a voltage doubler rectifier has a simple structure and its Zero-Voltage-Switching (ZVS) capability is excellent from zero to full load condition. But conduction loss is more due to high circulating energy thus reducing the system efficiency. Moreover a variable frequency control method makes the control circuits more complicated than ...

This paper presents the results of a research project dealing with the development of an adjustable converter for the injection of power generated by low voltage energy sources (primarily fuel cells used for decentral cogeneration of electric and thermal energy) into the public grid. The converters principle of operation is explained; measurements demonstrate the performance of the converter in...

A zero-voltage, zero-current switching (ZVZCS) PWM DC-DC power converter with secondary active rectifier tested as a dc current source for arc welding is described in this paper. The soft switching DC-DC converter consists of high frequency inverter, high frequency power transformer and controlled output rectifier with new secondary energy recovery turn-off snubber. Circulating current in the c...
