Abstract:	This paper presents a PQ four quadrant four-wire three-phase inverter for microgrids integration. The inverter is based in two full-bridge IGBT modules connected in a three-phase configuration plus a threephase parallelized neutral branch. This topology is galvanically isolated through a single-phase transformer bank. The converter operates as a non-ideal voltage-controlled voltage source inverter under AC droop strategy with hot-swap capability based on a dynamic virtual impedance.
