Aalborg Universitet Selective harmonic control for power converters
... THD. Since the RC control gain is designed as krc= 0.6, the SHC control gains are consequently designed as k1= 0.36, k2= 0.12, k0=k3= 0.06 for comparison according to (5) and (6) in order to achieve an accurate but fast control performance. Fig. 6 and Fig. 7 show the steady state response with the ...
