Direct Power Control Based on Three-Phase Shunt Hybrid Power Filter Case Study

The research based on shunt hybrid power filter in this paper is of better performance. Due to the limited switching frequency (typically below 1 kHz) of high-power solid-state devices (GTO/IGCT), current control is simplified by merging the use of synchronous reference frame (SRF) and instantaneous reactive power (IRP), and the vector algorithm without transformation matrix IRP is used in this paper. The reliability of this method has been verified by the simulation results based on MATLAB.
