electric arc furnace (eaf) is one of the largest loads in electric power systems. it is highly time varying and nonlinear. its reactive power variations cause voltage fluctuations in nearby system which is known as flicker. on the other hand the nonlinear voltage-current characteristic causes strong voltage and current harmonics in eaf. to this end flexible ac transmission systems (facts) techn...

In this paper, a series Z-source inverter based on switched inductors cell is proposed for the first time. This inverter is able to increase the voltage gain in comparison to the conventional Z–source inverters in additon to solve the ST (shoot-through) state’s problems. In this inverter, the value of voltage gain is increased by increasing the number of used diodes and inductors in the switche...

This article proposed a simple self cascode RGC amplifier configuration to increase the gain and bandwidth. The cascode amplifier eliminates the miller capacitance between input and output and facilitates high gain, high input and output impedance with high bandwidth. However, the cascode amplifier requires relatively high supply voltage for proper operation and it decreases the output voltage ...

Abstract The recent surge of interest in electrostatic actuators, particularly for soft robotic applications, has placed increasing demands on high voltage control technology. In this respect, optoelectronic bidirectional switching and analogue regulation voltages is becoming increasingly important. One common problem the leakage current due to dark resistance material or device used. Another p...

In today’s multimedia orientated society, display devices used as man-to-machine interfaces to facilitate communication have become an indispensable part of daily life in both the public and industrial sectors. CRTs (cathode ray tubes) are the most widely used electric display devices because they provide a low cost, large screen, full-color image with high resolution, high brightness, and quic...
