Comparative Study of Two Level and Three Level PWM-Rectifier with Voltage Oriented Control
Arezki Fekik,Hakim Denoun,Ahmad Taher Azar,Ahmad Taher Azar,Mohamed Lamine Hamida,Mustapha Zaouia,N. Benyahia +6 more
TL;DR: This article presents performance evaluation and comparison between Voltage Oriented Control methods for PWM-rectifiers, two levels and three levels, in order to demonstrate the great advantages of using a three-level Neutral Point Clamped (NPC).
Journal Article
The influence of maintenance quality of hemodialysis machines on hemodialysis efficiency.
TL;DR: In this paper, the impact of hemodialysis machine maintenance on dialysis adequacy Kt/V and session performance was evaluated on 134 patients on 3-times-per-week dialysis regimens by dividing the patients into four groups and also dividing the hemedialysis machines according to their year of installation.
