Fig. 1 Schematic diagram of a DSTATCOM connected Three Phase Four Wire System.
3. REFERENCE CURRENT GENERATION FOR DSTATCOM The reference current generation of DSTATCOM is carried out in three different modes:
  1. CCM operation
  2. VCM operation
  3. Dual Mode operation
  1. Reference current generation during CCM operation:Fig 2 shows the block diagram for generation of reference signal for CCM operation so that the source current is sinusoidal and in phase with the source voltage.
