This paper proposes a new high step-up DC–DC converter designed especially for regulating the dc interface between various micro sources and a dc–ac inverter to electricity grid. The need of Electricity increases the power demand where the power demand met by the conventional sources of energy has some disadvantage of pollution, this disadvantage can be decreased by the use of the Renewable ene...

in this article our objective is to obtain steady state characteristics of shunt, series, and separately excited dc motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. we assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. it is ...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

-A dc-dc converter has its applications, such as in hybrid vehicles, solar inverters, in power supplies for microprocessors etc. A bidirectional dc-dc converter can be alternately operated as a step down converter in one direction of energy flow and as step up converter in reverse direction of energy flow, in places where both the sides have voltage sources. A high voltage supply using a single...

This paper proposed to utilize the DC source from the solar PV. The DC/DC converter is the unidirectional power flow between the solar PV and load, while in existing its bidirectional. The proposed converter becomes compact using wide band gap devices which provide high efficiency and reduces heat generation of the circuit. PSO is used for the switching control for the converter. The converter ...

In this paper, a high step-up three-level DC–DC converter with symmetric structure for PV application is proposed. The has voltage gain. This achieved due to the use of two cells and resonant paths in its structure. low input current ripples stress across all switches equal half output voltage. proposed uses simple pulse–width modulation (PWM) trigger switches. Hence, benefits from control circ...
