Using A Synchronous Reference Frame (Srf)-Based Control Algorithm, This Paper Presents A Three-Phase, Four-Leg, Vsi-Based Ac Shunt D-Statcom Feeding Ac Voltage Controller With A Resistive-Inductive (Rl) Load For Maintaining Upf And Reducing Harmonic Current. When A Non-Linear Load Is Fed By A Three-Phase Source, This Theory Is Used To Calculate The Compensating Current. The Sim-Power System (Sps) Toolbox Is Used In The Matlab Environment To Simulate An Unbalanced Load In Pfc Mode.
