Undamped Control Strategy of Single-phase LCL Grid-connected Inverters
The digital control system delays the system, Considering the control delay and the resonance problem for LCL filter, a undamped control strategy of single-phase LCL type grid connected inverter is proposed. The grid connected current is controlled by network side current feedback. Not only the system unit power factor can be realized, but also no additional sensors are added, so the system control cost is reduced. The feasibility of undamped control is analyzed in detail, and the calculation procedure of controller parameters is given. An experimental platform is built. The correctness and effectiveness of the undamped control strategy are verified on the platform.
