This paper presents a thorough study of the adaptive sliding mode technique with application to single-phase shunt active power filter APF . Based on the basic principle of single-phase shunt APF, the approximate dynamic model is derived. Amodel reference adaptive sliding mode control algorithm is proposed to implement the harmonic compensation for the single-phase shunt APF. Thismethodwill use...

In power distribution networks, nonlinear loads produce harmonic currents that can pass through other sensitive locations in the power system and eventually back to the source. Harmonic currents can produce a variety of effects that are harmful to a power system structure. Consequentially, the deployment of new cost and energy efficient passive, active and hybrid filtering techniques is importa...

Today’s modern commercial and military communication systems are demanding better performance with regards to power, effi ciency, linearity and operating bandwidth. As such, extra considerations must be placed on designing the internal components of the systems, including the low-noise and power amplifi ers, to maximize performance. In order to reach higher effi ciencies, signifi cant research ...

Transformers are the basic and valuable equipment of electricity network. Transformers correct function has important role in reliability of network .distribution transformers are designed for work at nominal frequency and full sinus current. Application of nonlinear loads in recent decades, such as power electronic loads, caused higher levels of harmonic. This kind of load can lead to creating...

The supply current is distorted by the nonlinear load such UPS, DC drives, AC drives and arc furnace. This current harmonics derates the electrical equipments. Thus the current harmonics are reduced from the supply line using Shunt Hybrid filter. The Hysteresis controller controls the active filter thus the supply current tracks the reference fundamental current extracted by the synchronous ref...
