This paper proposes the virtual flux based direct power control for Vienna rectifier. No need for the input voltage sensors, the current regulation loop and PWM voltage modulation block along with the active and reactive power decoupling are some of the salient advantages of this method that make it suitable for controlling the conventional active rectifiers. However, due to the three-level nat...

This paper presents a review and analysis of multilevel inverter topologies. Multilevel inverters are most widely used for medium-voltage high-power converter like fans, pumps and material transport drives. In this active area, different inverter topologies, circuits, advantages and drawbacks are discussed. Multilevel Inverter topologies such as diode-clamped, flyingcapacitor, cascaded H-bridge...

This research will demonstrate feasibility for manufacturing fiber-based ceramic capacitors suitable for electrical energy storage within multifunctional textile products. Capacitive energy storage is well matched to applications requiring high specific power, long cycle life, and high reliability. We are using a simple chemical scheme for preparing fiber-based capacitors by coating electricall...

Due to concerns, such as global warming and depletion of fossil fuels, countries are forced integrate energy storage devices (ESSs) renewable sources (RESs), photovoltaic (PV) systems, wind turbines fuel cells, into their power networks. Here, a new high gain DC–DC converter with step-up/down ability is proposed for modern applications. Since this provides variable voltage gain, it can be emplo...

In the high-speed digital printed circuit board, decoupling capacitors play an important role in lowering the power-ground planes impedance leading to the ground bounce noise in I/O ports while the logic is in transition. This paper investigates the optimal placement of decoupling capacitors in suppressing the input and transfer impedances of power-ground planes. The cavity model combines with ...

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...

A model for MOS capacitors in accumulation is presented, which is able to predict the nonlinear distortion accurately. The key idea of this work is to include the polysilicon gate depletion effect in that model. Several test structures based on MOS capacitors in accumulation have been implemented with the object of validating the model and to explore the potential applications to high performan...

A new high input impedance voltage-mode universal biquadratic filter with three input terminals and five output terminals is presented. The proposed circuit uses three plus-type differential difference current conveyors, two grounded resistors and two grounded capacitors. The proposed circuit can realize all the standard filter functions: lowpass, bandpass, highpass, notch and allpass, without ...
