Continuous technological development facilitates the increase in the number of nonlinear loads that significantly affect the power quality in a power system and, consequently, the quality of the electric power delivered to other customers. One of the most common methods to prevent adverse effects of nonlinear loads on the power network is the use of passive filters. Design of such filter can be...

BACKGROUND Environmental tobacco smoke (ETS) is associated with human morbidity and mortality, particularly chronic obstructive pulmonary disease (COPD and lung cancer. Although direct DNA-damage is a leading pathomechanism in active smokers, passive smoking is enough to induce bronchial asthma, especially in children. Particulate matter (PM) demonstrably plays an important role in this ETS-ass...

In this paper, the synthesis of a dissipative complex filter is proposed. The proposed circuit is realized by using resistors, capacitors, and lossy transformers. As an example, a third-order complex filter is designed and its validity of the proposed method was confirmed through computer simulation. Keywords—dissipative, passive, analog, complex, filter

The use of switch mode power supply (SMPS) load such as computer, laptop, etc in residential well commercial areas give rise to harmonics pollution the electrical distribution system which causes quality poor and function equipment connected is affected. Many appliances have an SMPS design that characteristically draws a distorted current flows back input distortion voltage waveform. To ensure ...

Preliminary investigation on the feasibility of size selective passive sampling for atmospheric particles was undertaken through laboratory simulated and outdoor sampling. The passive samplers used in the research were improved from passive sampler used for sampling atmospheric organic contaminants. Sampled particle size distribution was analyzed by MasterSizer 2000 laser particle size analyzer...

A new circuit topology realizing a first-order currentmode all-pass filter is proposed using two dual-output second generation current conveyor and two passive components. The circuit possesses low-input and high-output impedance, which makes it ideal for current-mode systems. The proposed circuit is verified through PSPICE simulation results. Keywords—active filter, all-pass filter, current-mo...

This paper presents a three-phase hybrid power filter based on artificial intelligence control approach. It consists of C-type passive filter in parallel with a shunt active filter that is controlled by an adaptive Neuro-Fuzzy inference system (ANFIS) controller. The active filter is based on a three-phase voltage inverter with six control switches. The AC side of the filter is connected in par...
