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 ...

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...

High Step-Up Resonant DC-DC converter for High power Applications

This project, along with the voltage multiplier chain with dual coil output to the boost converter provides a novel parallel input. On the one hand, and to take part in the input current and to reduce input curre nt ripple in the two coils in parallel with the primary windings connected. On the other hand, it is proposed to change, and a series of interleaved output capacitors profit profitable...

Design and analysis of power-CMOS-gate-based switched-capacitor DC-DC converter with step-down and step-up modes

A unified multi-stage power-CMOS-transmission-gate-based quasi-switched-capacitor (QSC) DC-DC converter is proposed to integrate both step-down and step-up modes all in one circuit configuration for low-power applications. In this paper, by using power CMOS transmission gate as a bi-directional switch, the various topologies for step-down and step-up modes can be integrated in the same circuit ...
