دانلود ترجمه مقاله جنبه های بهبود کیفیت توان در سیستم درایو با استفاده از یک فیلتر اکتیو

The paper deals with a series of issues relative to power quality in drive systems and the behavior of a load composed from a uncontrolled rectifier, chopper and a DC motor. A MATLAB-Simulink scheme was designed in order to study the possibility to eliminate the unwanted power-related effects from the system. An equipment having the role of active filter is modeled and studied. The active filter is initialized through the charging of a capacitor. The initial voltage across the capacitor was increased by 30% by using an exponential filter. FFT analysis was also done in order to compare the values of currents flowing through the secondary winding of the uncontrolled rectifier’s transformer before and after filtering.
