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...

Harmony formation gives chance define ce...

From the last few years, generalized bent functions gain a lot of attention in research as they have many applications various fields such combinatorial design, sequence design theory, cryptography, CDMA communication, etc. A deep and broad study with their properties is done literature. Kumar et al.[11] first gave concept function. Many researchers studied characterizations functions. In [2] a...

A dynamical model for COVID-19 spread relating to non-pharmaceutical interventions and vaccination is mathematically generated by adding a gradual compartment the susceptible population considering only symptomatic infectious stage. In our model, there are seven compartments dividing given into , vaccinated src=image/17628733_02.gif>, exposed src=image/17628733_03...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....

in this paper, a novel approach for control of the dc-dc buck converter in high-power and low-voltage applications is proposed. designed method is developed according to state feedback linearization based controller , which is able to stabilize output voltage in a wide range of operation. it is clear that in high-power applications, parasitic elements of the converter may become comparable with...

active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. this paper proposes a control scheme based on the instantaneous active and reactive power. the inverter of this active filter is a three-phase, two-level converter. space vector technique is used as modulators and pattern genera...

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. ...

The objective of this paper is to propose bidirectional charging/discharging strategies for three-phase grid-tied converters. power flow control feature the converter able realize both charging and discharging capability. Besides, in order achieve high efficiency as well extend life battery, five are adopted developed: 1) constant current (CC) charging, 2) pulse-ripple-current (PRC) 3) sinusoid...

SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...
