  ABSTRACT: A simulation study between the DQO gate firing unit (GFU) and a proposed GFU for high voltage direct current (HVDC) rectifier based on the CIGRE benchmark model in Matlab/Simulink is carried out. The proposed GFU does not use traditional phase lock loop (PLL) and offers structural simplicity, fast response and immunity to ac system voltage unbalance, harmonics, voltage sag, frequency jump and phase jump etc. Since there is no loop filter, no tuning issues are involved. Advantages of the proposed GFU are confirmed by extensive simulation results.
