This study proposes a novel bidirectional isolated DC/DC converter with high gain ratio and wide input voltage for electric vehicle (EV) storage systems. The DC bus of an EV can be used to charge its battery, the battery pack discharge energy through when lacks power. range proposed is 24 58 V on low-voltage side, which meets specifications most servers batteries market. topology verified desig...

A retinal ganglion cell receptive field is made up of an excitatory center and an inhibitory surround. The surround has two components: one driven by horizontal cells at the first synaptic layer and one driven by amacrine cells at the second synaptic layer. Here we characterized how amacrine cells inhibit the center response of on- and off-center Y-type ganglion cells in the in vitro guinea pig...

This paper proposes a diamond-shaped high step-up switched-capacitor based basic multilevel inverter topology. The (SC) stage consists of 2 active switches, diodes, and capacitors. Using single DC source with the unfolding circuit (10 5 capacitors, diodes) results in production 17 voltage-steps at output gain up to 8 times input voltage. By extending stages, higher voltage levels gains can be p...

Class-AB circuits, which are able to deal with currents several orders of magnitude larger than their quiescent current, are good candidates for low-power and high slew-rate analog design. This paper presents a novel topology of a class AB flipped voltage follower (FVF) that has better slew rate and the same power consumption as the conventional class-AB FVF buffer previously presented in liter...

The DC open-loop voltage Gain is a very important specification for amplifiers. In order to increase this specification, in this paper, we have proposed an improved folded cascode gain boosted amplifier (improved FCGBA) which has extremely large DC open-loop voltage gain. Compared to traditional FCGBA, this novel structure needs only one auxiliary amplifier, so it is energy saving. Finally, wit...

A new organization of switched capacitor charge pump circuits based on voltage doubler structures is presented in this paper. Each voltage doubler takes a DC input and outputs a doubled DC voltage. By cascading n voltage doublers the output voltage increases up to 2 times. A two phase and a multiphase voltage doubler structures are proposed and their properties discussed. The multiphase voltage...

Photovoltaic and wind are renewable energy resources that widely used and grow rapidly in fulfilling electricity demand. Powers from both technologies depend on sunlight intensity and wind speed. For small scale power generation, DC voltage from both technologies is low and requires step-up converter to raise DC voltage ratio before converted into AC voltage. To optimize this system, step-up co...

It remains unclear how visual information is co-processed by different layers of neurons in the retina. In particular, relatively little is known how retina translates vast environmental light changes into neural responses of limited range. We began examining this question in a bottom-up way in a relatively simple fly eye. To gain understanding of how complex bio-molecular interactions govern t...

The Conventional Boost Converters is not possible to obtain the high voltage gain. In this paper a DCDC boost converter is proposed for achieving high voltage gain and to reduce the harmonic content in the output side. The circuit diagram of the proposed converter is consists of coupled inductor. Therefore the voltage stress on the active switch is reduced due to the presence of the inductor an...

This paper proposes a stand-alone photovoltaic (PV) system based on a DC-DC positive output super lift Luo (POSLL) converter. A conventional sliding mode control, a sliding mode controller using a simple sign function and a linear controller using proportional integrator (PI) are used for the control of the PV panel voltage and POSLL converter inductor current and these methods are compared tog...
