In thermoelectric coolers (TECs) applied external voltage potential is generated to a temperature difference based on the Peltier effect. Main and basic structure of TECs is in the form of single stage device. Due to the low efficiency, especially low coefficient of performance (COP) of thermoelectric coolers, optimal design of geometrical parameters of such devices is vital. For this purpose, ...

To develop a well designed practical spring-roll dielectric elastomer actuator system, we have to optimize its design parameters. In our pervious work, we have achieved the design parameters without taking the applied voltage required to activate the actuator into consideration because the applied voltage might change the optimal design parameters. In the paper, optimal design parameters have b...

This work presents an thorough analysis and design of a low-voltage low-power voltage reference circuit with sub-bandgap output voltage. The outcome of the analysis and the resulting design rules are universal and it is supposed to be general and suitable for similar topologies with just minor modifications. The general analysis is followed by a selection of specific topology. The given topolog...

this paper deals with the design and evaluation of a robust controller for static var compensator (svc) in remote industrial power systems to enhance the voltage profile for three-phase single cage induction motor (scim) loads. the controller design is based on h∞ theory to deal with uncertainties arising in industrial network modelling. the performance of the h∞ controller has been evaluated e...

As the operating supply voltage for commercial CMOS devices falls below 2 V, research activities are underway to develop CMOS integrated circuits that can operate at supply voltages well under 1 V. Although dramatic power reductions can be achieved using low supply voltages in high performance applications, the increased subthreshold leakage that results when transistor threshold voltages are l...

This paper presents the analysin ,design and implementation of a high voltage ratio topology of DC-DC converter. The DC-DC converter has high voltage ratio with reduced input current, output voltage and output current ripple, and also reduces the voltage and current rating of power electronics components and compared with conventional boost converter. The voltage stress on the switches are  red...
