PROBLEM TO BE SOLVED: To provide a matrix converter and a method for compensating an output voltage error, capable of suppressing with high accuracy an output voltage error produced by commutation control, without correction of a voltage command.SOLUTION: The matrix converter includes a command generator and a commutation controller. The command generator generates a control command to specify a PWM control pulse width, on the basis of the voltage command. The commutation controller performs commutation control by controlling a switching element with a predetermined commutation method. The command generator includes a corrector for correcting the pulse width obtained from the voltage command so as to reduce an output voltage error produced by the commutation control, and for generating the control command. |
