Zusammenfassung:	The utility model provides a weak power grid simulator based on a series active H-bridge converter, which comprises a power grid simulator and an active H-bridge inverter, the positive output end of the active H-bridge inverter is electrically connected with the power grid simulator through a PCC point, the negative output end of the active H-bridge inverter is connected with the positive output end of the alternating current side of the power grid simulator, and the positive output end of the alternating current side of the power grid simulator is electrically connected with the positive output end of the alternating current side of the active H-bridge inverter. The output end of the active H-bridge inverter is electrically connected with a tested system. The structure of the series H-bridge converter not only can accurately simulate the line impedance, but also does not influence the stability of the original system due to the adoption of a series mode, and meanwhile, the simulation parameter range is not l
