N2 - In the control of matrix converter, multi-step current commutation from one input phase to another needs dead-time for safe commutation, so like the dead-time effect in VSI, there is unwanted output voltage error occurred. In this paper, first, the widely used multi-step current commutation's procedure and the corresponding output voltage error under the space vector modulation(SVM) is analyzed, then, the scheme of dead-time compensation based on the improved SVM is proposed, the scheme compensates the output voltage error by correcting the space vector's duty time. The experimental results show that the scheme is not only available but also it add no hardware to the system, and it is easy to be fulfilled by the control system.
