Abstract:
A method of commutation in a matrix rectifier from an active vector to a zero vector includes two steps. A method of commutation in a matrix rectifier from a zero vector to an active vector includes three steps.

Claim (Index 1):
A matrix rectifier comprising:\n first, second, and third phases; and uni-directional switches Sij, where i=1, 2 and j=1, 2, 3, 4, 5, 6 and where uni-directional switches S 1 j  and S 2 j  are connected together to define first, second, third, fourth, fifth, and sixth bi-directional switches; wherein first ends of the first, third, and fifth bidirectional switches are connected together to provide a positive-voltage node; first ends of the second, fourth, and sixth bidirectional switches are connected together to provide a negative-voltage node; second ends of the first and fourth bidirectional switches are connected to the first phase; second ends of the third and sixth bidirectional switches are connected to the second phase; second ends of the fifth and second bidirectional switches are connected to the third phase; a zero vector is defined by either uni-directional switches S 1 m  and S 1 n  switched on or unidirectional switches S 2 m  and S 2 n  switched on, where (m, n)=(1, 4), (3, 6), (5, 2), and by all other uni-directional switches Spq switched off, where p\u2260m and q\u2260n; an active vector is defined by either uni-directional switches S 1 m  and S 1 n  switched on or uni-directional switches S 2 m  and S 2 n  switched on, where m=1, 3, 5; n=2, 4, 6; and m, n are not connected to the same phase, and by all other uni-directional switches Spq switched off, where p\u2260m and q\u2260n; Sectors I, II, III, IV, V, and VI are defined by using active vectors with (a, b)=(1, 6), (1, 2), (3, 2), (3, 4), (5, 4), and (5, 6); commutation from an active vector to a zero vector includes: step (a):\n for an active vector with uni-directional switches S 1 m  and S 1 n  switched on,\n in Sectors I, III, V, turning on uni-directional switch S 1 x , where x is chosen such that (m, x)=(1, 4), (3, 6), (5, 2); and \n in Sectors II, IV, VI, turning on uni-directional switch S 1 x , where x is chosen such that (x, n)=(1, 4), (3, 6), (5, 2); or \n \n for an active vector with uni-directional switches S 2 m  and S 2 n  switched on,\n in Sectors I, III, V, turning on uni-directional switch S 2 y , where y is chosen such that (y, n)=(1, 4), (3, 6), (5, 2); and \n in Sectors II, IV, VI, turning on uni-directional switch S 2 y , where y is chosen such that (m, y)=(1, 4), (3, 6), (5, 2); and \n \n step (b):\n for the active vector with uni-directional switches S 1 m  and S 1 n  initially switched on,\n in Sectors I, III, V, turning off uni-directional switch S 1 n ; and \n in Sectors II, IV, VI, turning off uni-directional switch S 1 m ; or \n \n for the active vector with uni-directional switches S 2 m  and S 2 n  initially switched on,\n in Sectors I, III, V, turning off uni-directional switch S 2 m;  \n in Sectors II, IV, VI, turning off uni-directional switch S 2 n;  \n \n the commutation includes measuring output voltage and not measuring output current or input voltage.
