An Efficient High-Step-Up Soft-Switching Boost Converter for Photovoltaic Application

In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...

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 ...

Simulation of ZVZCS Based DC-DC Boost Converter

This paper presents the design and simulation of the zero voltage zero current switched non isolated dcdc boost converter. Many applications powered by batteries need high performance, high step up dc-dc converters. When the converter switches are turned on and off at high frequency to meet dynamic and steady state requirements, the losses add on in the converter. When current through the switc...

An Efficiency Step-Up Converter with a Low Switch Stress

A novel approach is proposed for a high step-up and high efficiency converters with a low switch stress. The integrated boost-flyback converter uses coupled-inductor techniques to achieve high step-up voltage with low duty ratio, and thus the slope compensation circuit is disregarded. The proposed circuit topology improving highgain ratio, increasing efficiency, reducing the secondary side of c...
