In recent years, the use of electroporation process has attracted much attention, due to its application in various industrial and medical fields. Electroporation is a microbiology technique which creates tiny holes cell membrane by applied electric field. The needs high-voltage pulses provide required To generate pulses, pulse generator device must be used. High-voltage generators can mainly d...

A wide-view single cell gap transflective liquid-crystal display (TR-LCD) using the fringe field switching effect is proposed by incorporating a quarter-wave in-cell-retarder below the liquid-crystal (LC) cell in the reflective part. By optimizing the angle between the electrode stripes and the LC rubbing direction in the transmissive and the reflective regions, this TR-LCD exhibits a high opti...

A new zero voltage switching current fed zero-voltage switching isolated boost converter topology for fuel cell applications is presented. L-type half-bridge is more suitable to low voltage, high current applications such as front-end dc–dc converters for the fuel cell applications. It has larger switch voltage rating and also suffers from high voltage across the switches. Clamping methods are ...

A current-fed LLC resonant converter is proposed for high-voltage and high-power applications. Here, a two-phase interleaved structure used in the input stage under continuous conduction mode (CCM) to effectively reduce current output voltage ripple values filter capacitors volumes. Due expandable high gain, configuration suitable applications since low stresses are applied across its component...

flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biologicalinsects and useful for a wide range of tasks, including exploration, environmental monitoring, searchand rescue, and surveillance. recently, robotic insects driven by piezoelectric actuators have achievedthe important goal of taking off with external power; however, fully autonomous operation requir...

in this paper, a dc-dc resonant converter with high voltage gain and small size is studied. to reduce the size and weight of this converter, the operating frequency should be as high as possible. in this research, the frequency changes from 120 to 200 khz. due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. resonant converters are su...
