this paper presents a detailed small-signal and transient analysis of a full bridge pwm dc-dc converter designed for high voltage, high power applications using an average model. the derived model is implemented in a typical system and used to produce the small-signal and transient characteristics of the converter. results obtained in the analysis of the high voltage and high power design examp...

  The involvement of NMDA receptors and voltage-dependent calcium channels in augmentation of long-term potentiation (LTP) was investigated at the Schaffer collateral CA1 pyramidal cell synapses in hippocampal slices of morphine dependent rats, using primed-burst tetanic simulation. The amplitude of the population spike and its delay were measured as indices of increase in postsynaptic excitabi...

Electrolytic manganese dioxide (EMD) was prepared by using gas diffusion electrode (GDE) instead of traditional hydrogen evolution cathode. Sulfate acid’s effects on the cell voltage, the current efficiency, the electro-catalytic activity and the lifetime of GDE are studied. The results show that as the concentration of sulfuric acid increases, the current efficiency increases, while the cell v...

This paper presents the different types of analysis such as noise, voltage, read margin and write margin of Static Random Access Memory (SRAM) cell for high-speed application. The design is based upon the 0.18 μm CMOS process technology. Static Noise Margin (SNM) is the most important parameter for memory design. SNM, which affects both read and write margin, is related to the threshold voltage...

a new output structure for class e power amplifier (pa) is proposed in this paper. a series lc resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. this resonator causes low impedance at the second harmonic. the output circuit is designed to shape the switch voltage of the class e amplifier and lower the voltage stress of the transistor. t...

In electric vehicles, voltage and temperature sensors installed at the battery cell level or pack are crucial for providing accurate information so management system (BMS) can perform its functions properly. this paper, a model-based sensor fault estimation scheme using sliding mode technique has been proposed. Voltage models have developed Lithium-ion cell. Then, observer proposed to estimate ...

An 18 μm thin crystalline silicon solar cell was demonstrated, and its best open circuit voltage is 642.3 mV. However, this value is far from the cell’s theoretical upper limit in an ideal case. This paper explores the open circuit voltage losses of the thin silicon solar cell, starting from the ideal case, through first principle calculation and experiments. The open circuit voltage losses com...

The properties of light-activated and voltage dependent conductances in the hyperpolarizing photoreceptors of the isolated retina of the giant scallop (Patinopecten yessoensis) have been studied in whole-cell voltage-clamp recordings. Resting membrane potential of the cells was -35 to -60 mV in the dark. Large outward current was maintained during illumination when the cell was voltage clamped ...
