Abstract The indirect space vector modulation(ISVM) approach of matrix converters(MC) is researched firstly. In ISVM, complex coordinate transformation is required to acquire relevant control variable in fictitious rectifier and fictitious inverter, and sectors judgment and quantity of trigonometric operations are involved in the modulation process. In this paper, trigonometric function analysis is applied to detect the signal relations directly, moreover, a novel sector judging and duty cycle calculation method in fictitious rectifier and fictitious inverter is proposed. Comparing with the traditional ISVM, this method can omits the α-β coordinate and polar coordinate transformation, thus, greatly simplify the calculation process and enhance the real-time performance. The feasibility and validity of the new approach is verified by both simulation and experimental results.

Key words： Matrix converter space vector pulse width modulation fictitious rectifier fictitious inverter duty cycle
