An Interleaved Configuration of Modified KY Converter with High Conversion Ratio for Renewable Energy Applications; Design, Analysis and Implementation

In this paper, a new high efficiency, high step-up, non-isolated, interleaved DC-DC converter for renewable energy applications is presented. In the suggested topology, two modified step-up KY converters are interleaved to obtain a high conversion ratio without the use of coupled inductors. In comparison with the conventional interleaved DC-DC converters such as boost, buck-boost, SEPIC, ZETA a...

A Multi-port High Step-up DC/DC Converter for Hybrid Renewable Energy Application

This paper presents a novel multi-port DC/DC converter which is suitable to be used as the interface of hybrid renewable energy systems. The converter contains three unidirectional power flow ports which two of them are input ports and are connected to two independent energy sources while the third one is the output port that feeds a standalone load. Furthermore, the proposed converter contains...

Dual Input Dual Output Converter for Renewable Energy Applications

With the increasing fossil fuel exhaustion, environmental pollution and global energy demand, the use of renewable energy based clean and non-pollutant energy sources are gaining more importance. Since these sources are highly intermittent in nature, power electronic interfaces are necessary for their efficient utilization. For stand-alone applications, energy storage devices are required for b...

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...
