... thePI controller to determine theÆphase, and then it is fed to thegate controller to generate the gate signals. AÆphase limiteris applied to keepÆphase in the operating area.V. RESULTS ... sensors areused, which are fed to the control board. Phase lock loop(PLL) technique is applied to synchronize the gate switchingtime to the phase of the line voltage.For feedback control, the ... (c) parallel path timethe system and then it is called SVC MERS. For three phasesystems there will be one SVC MERS per phase.B. Operation PrincipleOperational states to control upward current...
