Advantages of AC over DC The following are some of the merits of AC compared to DC: First, the AC can transport more power over a shorter distance compared to DC. This capability is because, unlike DC, which flows in a straight line, power moves in a waveform, which is significantly ea...
In this paper, the maximum transfer capability of an AC system and two DC systems, one with two lines and another with three, is determined through the continuation power flow method and compared. The results reveal that significant gains can be achieved by moving to a DC system with three ...
Hello everyone, I am Rose. Welcome to the new post today. This article mainly introduce the definition of AC and DC, AC/DC Converter as well as DC/DC ...
which is typically alternating current, must be converted to direct current. This conversion from AC to DC can take place either via the on-board charger in the electric vehicle or directly at the charging station. Depending on the method, this is referred to as AC or DC charging. ...
The proposed AC-DC circuit improves the power quality compared to the conventional circuit. It raises the efficiency above 95%, increases the power factor (PF) by 6% compared to the conventional circuit and improve the total harmonic distortion (THD) by 2-3% with respect to the conventional ...

Two high efficiency DC-to-AC inverters for stand alone and direct AC mains connection are described and compared. The structures use only off-line switches to generate the AC voltage. The overall efficiency of the inverters depend to a high degree on the number of switching elements in the ...
Power Electronic Transformers (PET) offer the advantage of size and weight reduction compared to line frequency transformers by operating at much higher frequencies than line frequency. In this paper, a push-pull based AC/DC PET has been proposed and analyzed. The PET offers bidirectional power fl...
Subjects related with the amplification of the harmonic magnitudes are investigated and compared considering similar arrangements of conventional static converters (LCC) and CCC schemes. It is also analyzed the harmonic generation on the DC side of the installation and its influence on the AC side ...
Chemisorptive adsorption is more probable in this case. The lower value of activation energy in the presence of 1-benzyl-benzimidazole when compared to that in 1 M HCl is explained with a partial compensation effect. 展开 关键词: Corrosion Electrochemical impedance spectroscopy Inhibitors Temperature ...
