Parametric average-value modeling of AC-AC matrix converters

Matrix converters are becoming increasingly considered in AC-AC energy conversion applications where they can supply loads with variable voltages in a broad range of frequencies. For simulation of power systems, detailed models of these switching converters can be utilized. Despite providing high accuracy, the detailed models introduce a large number of discrete switching events in the simulation. Handling all the repeated switching slows down the simulation, creating a great challenge for system-level computer studies. To alleviate this computational burden, the so-called parametric average-value modeling (PAVM) technique has been developed to provide sufficiently accurate and fast models of power electronic converters. In the past, the PAVM has been extensively developed for DC-DC and AC-DC converters and systems with their applications. In this paper, the PAVM methodology is extended to model AC-AC matrix converters. Excellent accuracy and superior numerical performance of the proposed PAVM of matrix converter are verified against the detailed model.
