Here, a new two-input step-up DC–DC converter for electric vehicles (EVs) and renewable energy systems (RESs) is proposed. It requires few components provides high voltage gain efficiency. The topology includes two input channels connected to sources based on the “switch-mode coupling” method. Sources supply load via proposed converter. Each source can charge another if it rechargeable. regener...

A novel modified bridge-type dual input DC-DC converter, which is proficient for integrating distinct V-I characteristic sources such as solar-PV, wind, etc., and storages including battery, ultracapacitor, fuel cell, etc., is proposed in this paper. Three modes of operations such as boost, buck, and buck-boost are possible using the same structure of the converter, and the converter can operat...

Present specifications for computer power supplies for networking applications call for designs with dual inputs: the universal ac-line input and the 48-V nominal dc input. In this paper, a design and evaluation of the dc-input version of a 900W server power supply is presented. The dc-input version of this power supply is leveraged from the ac-input version by using the same output stage, and ...

Input-series-output-parallel (ISOP) converters consisting of multiple modular DC/DC converters can enable low voltage rating switches to be used under high voltage input applications. This paper presents a digital control strategy, which can achieve equal sharing of input voltage for a modular ISOP system consisting of two-transistor forward DC/DC converters by forcing the input voltages of nei...

Received Feb 3, 2017 Revised Mar 18, 2017 Accepted May 5, 2017 Dual input dc-dc converters have two input voltage sources or one input source and an energy storage system like ultra capacitor, PV, battery, super capacitors and a single output load. In order to process the power in hybrid energy systems using reduced part count, researchers have proposed several multi-input dc-dc power converter...

The goal of this work is to reduce the DC-link capacitance of a two-stage single-phase inverter so much that the use of film capacitors becomes feasible in both, price and volume. Film capacitors instead of electrolytic capacitors could increase lifetime and reliability of the inverter, especially in high-temperature applications like module-integrated micro-inverters. For the capacitance reduc...
