In this paper, the comparisons of different hybrid inverters are provided for power quality compensation and/or active inverter injection. In detail, the characteristics are compared for inductive coupling grid connected inverter (IGCI), capacitive coupling grid connected inverter (CGCI), static var compensator (SVC) in parallel with a CGCI (SVC//CGCI), and hybrid grid connected inverter (HGCI). The comparisons are separately provided for two applications: 1) power quality compensation 2) both power quality compensation and active power injection. In this paper, the circuit configurations of different inverters are proposed firstly. Then, the design of each hybrid inverters is provided. After that, the comparisons are provided for above mentioned applications. Finally, the simulation results are provided to verify the characteristics of different hybrid inverters.
