Harmonic filtration by current injection and shunt capacitors technique
2013 3rd International Conference on Electric Power and Energy Conversion Systems, 2013The controlled and uncontrolled converters or inverters loads are widely used in industrial applications and especially in producing electric energy from renewable sources. These types of nonlinear loads generate harmonics, with damaged effects, lead to voltage and current distortion at utility and load sides, in addition to high amount of losses in ...

Determination of charge injection barrier using the displacement current measurement technique
Organic Electronics, 2016Abstract A new technique to determine the injection barrier using displacement current measurement (DCM) is reported. This technique was applied to junctions of metal-free phthalocyanine (H 2 Pc)/Ag and H 2 Pc/MoO 3 /Ag. The injection barriers from Ag to the highest occupied molecular orbital of H 2 Pc and to the lowest unoccupied molecular orbital ...

Augmentation of Power Quality Engaging Current Injection Technique via PI Controller
2018 International Conference on Electrical, Electronics, Communication, Computer, and Optimization Techniques (ICEECCOT), 2018This work exhibits a new approach for the reduction of harmonic content through three-phase system which is produced by non-linear loads. Due to enhancement in semiconductor technology, the converters and inverters play a major role in producing distorted waveforms and sometimes they may act as non-linear loads.
