Most existing power  converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...

In this paper, a SVM classifier based on S-Transform is presented for power quality disturbances classification. Firstly, seven types of PQ events are created using Matlab simulation. These signals are analyzed to detect and localize PQ events via S-Transform by visual inspection. Then five significant features of the PQ disturbances are extracted from the S-Transform output. Afterwards, PQ dis...

Distributed Generations (DGs) are utilized to supply the active and reactive power in the transmission and distribution systems. These types of power sources have many benefits such as power quality enhancement, voltage deviation reduction, power loss reduction, load shedding reduction, reliability improvement, etc. In order to reach the above benefits, the optimal placement and sizing of DG is...

Bridging faults in CMOS circuits sometimes degrade the output voltage and time performance without altering the logic function. The traditional voltage testing models based on the normal power supply voltage do not accurately model this behavior. In this paper we develop a model of bridging faults that accounts for both the bridging resistance distribution and gate sensitization and propagation...

The principles of the Internet-technologies use for ensuring operational safety of power supply of breakage faces of coal mines with a problems solution of design, training and employees' knowledge assessment of electromechanical services are considered. The technology of the coal dredging from inclined and flat layers of average and above average power assumes that at the movement of a breakag...

A circuit of a multi-phase active power filter based on multi-stage inverter architecture was introduced. The paper is focused on building the MATLAB / Simulink model of an AC power supply system including a single-phase active power filter with a two-stage inverter. Each stage of the filter uses the pulsewidth modulation (PWM) method. The results confirmed high efficiency of such a compensatin...
