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 Novel Bidirectional DC - DC Converter with Battery Protection

This paper presents the implementation of a bidirectional dc-dc converter to protect a battery from overcharging and undercharging. The proposed converter circuit provides low voltage stresses across the switches, higher step-up and step-down voltage gains and efficiency is also high when compared to conventional boost/buck converter. The proposed control circuit controls the charging and disch...

A Novel Interleaved DC-DC Converter with Reduced Loss for Fuel Cell Vehicle Application

In this paper a novel four-leg interleaved DC-DC boost converter is proposed which is well suitable for fuel cell vehicles (FCV) application. The voltage stress of two switches of this converter is half of the conventional interleaved converters. Therefore, smaller and cheaper switches can be utilized. Also "on" state duration of the two of four switches are reduced in comparison with...

Bidirectional Battery Charger for PV Using Interleaved Fourport DC-DC Converter

In this paper, a four-port bidirectional dc-dc converter is proposed for grid-interactive photovoltaic (PV) system application. The four-phase topology is suitable for residential pumping, aerospace power requirements. The control of battery and different capacities of PV modules are naturally decoupled. In addition, the port interface with PV is current type which can implement maximum power p...
