In this paper, a single-phase Seven-Level and Five-Level cascaded H-Bridge Inverter (CHB) based Distribution Static Compensator (DSTATCOM) is presented. A simple control algorithm based on inverse park PLL was proposed for both five-level and seven-level inverters. Synchronous Reference Frame theory (SRF) as control algorithm is used for reference source current extraction and to generate gatin...

The present study attempt to investigate the changes of the electroencephalogram (EEG) rhythms due to physical fatigue. Three different methods to enhance EEG signals have been applied. Aside from the Referential method, the Common Average Reference method as well as the Current Source Density method has been applied to the raw data prior to processing. Ten subjects participated in this study. ...

Shunt Active Power Filters (SAPFs) represent the most important and widely used filter in industrial purposes due to the fact that, they not only eliminate the harmonic current with a neglected amount of active fundamental current supplied to compensate system losses, but also they are suitable for a wide range of power ratings. One of the key issues for a proper implementation of an active fil...

Colour harmony was investigated using direct visual observations of computer simulated displays and compared with predictions of different colour harmony theories. Ou and Luo [1] constructed a model of colour harmony (CH formula) based on a harmony pair comparison experiment. The present paper compares our results with harmony predictions of the CH formula, and of colour harmony models based on...

The application of power semiconductor devices in the area of power electronics and power system are the key factors which kindle the power quality problems particularly the harmonics, burden of reactive power and neutral current due to unbalance. The above citied power quality problems are predominant due to wide usage of 1-φ / 3-φ , linear and nonlinear loads which are fed from three phase fo...

This paper presents modeling and analysis of 12-phase distribution static compensator (DSTATCOM), which is capable of balancing the source currents in spite of unbalanced loading and phase outages. In addition to balance the supply current, the power factor can be set to a desired value. The theory of instantaneous symmetrical components is used to generate the twelve-phase reference currents. ...

The quality of the current waveform generated by a current controlled, voltage source shunt active power filter depends basically on three factors: (i) The reference signal being generated; (ii) the modulation method used and (iii) the switching frequency of the PWM modulator. A new adaptive hysteresis band modulation method is proposed. In this paper, the periodical sampling constant hysteresi...
