The mass usage of traditional fossil energy has adversely affected the environment on a global scale, such as environmental pollution and greenhouse effect. Meanwhile, there has been a growing demand for energy with the development of society. Since traditional fossil energy is not renewable, it is faced with the problem of energy shortage. Solar energy and hydrogen energy are promising, and ph...

Soft switching of DC-DC converter is done here. This is obtain good efficiency and to reduce the switching losses. Zero voltage switching reduces the switching losses in the circuit. This is done by using boost converter. Soft-switching characteristic of the proposed converter reduces switching loss of active power switches and raises the conversion efficiency. A voltage step-up function and a ...

A low-voltage and low-power RF mixer for WCDMA applications is presented. The paper presents a novel topology mixer that leads to a better performance in terms of isolation and power consumption for low supply voltage. The measuring results of the proposed mixer achieve: 7dB power conversion gain, 10.4dB double side band (DSB) noise figure, -2dBm input third-order intercept point (IIP3), and th...

Modulating the gain of the input-output function of neurons is critical for processing of stimuli and network dynamics. Previous gain control mechanisms have suggested that voltage fluctuations play a key role in determining neuronal gain in vivo. Here we show that, under increased membrane conductance, voltage fluctuations restore Na(+) current and reduce spike frequency adaptation in rat hipp...

In order to generate electricity from solar PV modules, this study proposed a novel high-voltage gain step-up (HVGSU) DC–DC converter for photovoltaic system operation with maximum power point (MPP) tracker. The array can supply the load via converter, increasing output voltage. Due stochastic nature of energy, arrays must use MPPT control approach function at MPP. This suggests HVGSU that uses...
