| description | [Problem] To provide a space vector modulation method for a matrix converter which uses only one carrier for three phases when a carrier comparison is made. [Means for solving problem] Provided is a matrix converter space vector modulation method in which bidirectional switches (SW1 through SW9) of a matrix converter (3) are PWM controlled in a space vector modulation from a multi-phase AC power source. Switching patterns for which virtual indirect space vectors are used are converted into switching patterns for which direct conversion space vectors constituted by five vectors are used. Any one of the converted switching patterns satisfying predetermined conditions is selected and duties of the five vectors of the selected switching pattern are calculated using duty relationship equations between the virtual indirect conversion space vectors and the direct conversion space vectors. Then, the matrix converter is PWM-controlled on a basis of the calculated duties. |
