Claim 1:
2. The matrix power conversion device according to claim 1, wherein if the controller identifies that the base voltage command is positive, the controller is further configured to:
retrieve a time of the first linear carrier wave being greater than all the output expected values respectively, so as to acquire intermediate duty ratios corresponding to all the output expected values respectively;
retrieve a first time of the first linear carrier wave being less than all the output expected values respectively, and retrieve a second time of the second linear carrier wave being less than all the output expected values respectively;
add the first time to the corresponding second time, so as to acquire maximum duty ratios corresponding to all the output expected values respectively; and
retrieve a time of the second linear carrier wave being greater than all the output expected values respectively, so as to acquire minimum duty ratios corresponding to all the output expected values respectively.
