چکیده انگلیسی مقاله:
This paper describes a hybrid active filter intended for mitigating the line-side harmonic currents of a three-phase 12-pulse diode rectifier used as the front end of a medium-voltage high-power motor drive. This hybrid filter is characterized by se-ries connection of a simpleLCfilter and a small-rated active fil-ter. This circuit configuration brings low cost, small size, and light weight to the hybrid filter. A three-phase experimental system rated at 400 V and 15 kW is designed, constructed, and tested, which is a downscaled model of the medium-voltage motor drive system. In this experiment, the LCfilter is tuned to the 11th-harmonic frequency, and the active filter is based on a three-level neutral-point-clamped pulsewidth modulation converter (NPC PWM) with a dc capacitor voltage as low as 28 V. This hybrid filter is connected on either first or fourth winding of a line-frequency transformer with a firstΔ-winding voltage of 400 V in the primary, and a sec-ondΔ-winding voltage of 220 V, a third Y-winding voltage of 220 V, and a fourthΔ-winding voltage of 400 V in the secondary. Ex-perimental results show that the hybrid filter performs satisfactory filtering in a range from no-load to full-load conditions.
