Comparative Simulation Analysis on High Gain Bidirectional and High Step-up DCDC Converters

High-Efficiency, High Step-Up DC–DC Converters

Many applications call for high step-up dc–dc converters that do not require isolation. Some dc–dc converters can provide high step-up voltage gain, but with the penalty of either an extreme duty ratio or a large amount of circulating energy. DC–DC converters with coupled inductors can provide high voltage gain, but their efficiency is degraded by the losses associated with leakage inductors. C...

High efficiency high step-up DC/DC converters – a review

The renewable energy sources such as PV modules, fuel cells or energy storage devices such as super capacitors or batteries deliver output voltage at the range of around 12 to 70 VDC. In order to connect them to the grid the voltage level should be adjusted according to the electrical network standards in the countries. First of all the voltage should be stepped up to sufficient level at which ...

Design of a non-isolated multi-input converter with soft switching and high step-up voltage gain

Energy is one of the most important factors for the economic growth and development of each country. Most of the energy is consumed in the form of electricity. One of the most important ways to generate electricity is to produce electricity through fossil fuels. However, due to their disadvantages such as limitations and concerns about the environment and increased demand for energy, engineers ...

Bidirectional High Gain Antenna for Wlan Applications

Abstract—A bidirectional high gain four-element printed dipole array for WLAN (2.4/5.8GHz) applications is analyzed and successfully implemented in this paper. Each element used is a double-side printed dipole fed with a balance twin-lead transmission line. A wide-band balun is implemented for the dipole array. Both simulated and measured data are pretty matched. According to the measured resul...
