In this paper, a direct power control (DPC)
\r\nstrategies have been investigated in order to control a high
\r\npower AC\/DC converter with time variable load. This converter
\r\nis composed of a three level three phase neutral point clamped
\r\n(NPC) converter as rectifier and an H-bridge four quadrant
\r\ncurrent control converter. In the high power application,
\r\ncontroller not only must adjust the desire outputs but also
\r\ndecrease the level of distortions which are injected to the network
\r\nfrom the converter. Regarding to this reason and nonlinearity
\r\nof the power electronic converter, the conventional controllers
\r\ncannot achieve appropriate responses. In this research, the
\r\nprecise mathematical analysis has been employed to design the
\r\nappropriate controller in order to control the time variable
\r\nload. A DPC controller has been proposed and simulated using
\r\nMatlab\/ Simulink. In order to verify the simulation result, a real
\r\ntime simulator- OPAL-RT- has been employed. In this paper,
\r\nthe dynamic response and stability of the high power NPC
\r\nwith variable load has been investigated and compared with
\r\nconventional types using a real time simulator. The results proved
\r\nthat the DPC controller is more stable and has more precise
\r\noutputs in comparison with conventional controller.<\/p>\r\n","references":"[1] M. Malinowski, M. P. Kazmierkowski, S. Hansen, F. Blaabjerg, and\r\nG.
