Research of One-Step Commutation Strategy in Matrix Rectifier

Article Preview

Abstract:

Due to the absence of natural free-wheeling paths, the commutation in matrix rectifiers is much more complicated than in the other kinds of AC-DC converters. In this paper, based on the measurement of the output current direction and the signs of the input line-to-line voltages, a new one-step commutation strategy is applied in the design of matrix rectifier. Experimental results show that the new method is valid and feasible, founding a basis of further practical application.
