Description
Summary:	In this paper the design of synchronous frame DQ control based double loop control for single phase inverter in distributed generation system is proposed. For synchronous frame control, the orthogonal signal is generated by second order generalized integrator method. In Dual-loop control systems, the inner capacitor current feedback control and outer synchronous frame control is used to achieve better performance with zero steady state error. The better performance of load is achieved by providing load current as an additional feedback instead of using inductor current feedback. The proposed system is simulated using Matlab and results were presented. The designed controller gives the inverter output voltage with good transient response and reduced harmonic distortion.
