Abstract
In this paper, an active damping control scheme using the PR (proportional and resonant) regulator is proposed to eliminate the resonance for the grid-connected T-type three-level PWM converter systems with LLCL filter by which the total inductance can be reduced compared with the conventional LCL filters. The simulation results have verified the validity of the proposed control algorithm for a 25-kW three-phase T-type converter.
