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 Voltage Gain Converter with Ripple-free Input Current for Renewable Energy Sources

High step-up voltage gain nonisolated DC-DC converter have attracted much attention in photovoltaic, fuel cells and other renewable energy system applications. In this paper, by combining input current ripple-free boost cell with coupled-inductor voltage-doubler cell, an input current ripple-free high voltage gain nonisolated converter is proposed. In addition, passive lossless clamp circuit is...

High Step-up Converter with Diode Capacitor Technique for Renewable Energy Applications

This paper presents a high step-up boost converter with diode capacitor technique. In this topology an additional stage of voltage multiplier cells (diodes and capacitors) is incorporated into the conventional boost converter which will increase the voltage gain and efficiency of the converter. The peculiarity of this new method is that the switching losses, ripples and the stresses are low. An...

High Step up Switched Capacitor Inductor DC- DC Converter for UPS System with Renewable Energy Source

A new converter using a switched-inductor cell integrated with a switched-capacitor cell within a boost-like structure is proposed. The converter can achieve a very high dc conversion ratio. It can serve as the front-end dc-dc converter for a fuel cell in a UPS system. The inductors and capacitors are switched in a parallel-series configuration. The charging circuit of the inductors from the so...

Hybrid Energy System using Three Port Converter

Three Port Converters are used for merging more than a single source in order to improve the power handling capability. Here the first two ports acts as the sources and the third port acts as the output or to the Load. The objective is combining the Wind Energy Systems with the Existing Three Port Converter System instead of a Battery Storage. The proposed system is simulated and verified using...
