When first drive signals (Sup*, Sun*, Svp*, Svn*, Swp*, Swn*) are driving signals for applying a short-circuit mode for turning on a plurality of switching elements of the same output phase, the current source power conversion apparatus (1) according to one embodiment generates second drive signals (Sup**, Sun**, Svp**, Svn**, Swp**, Swn**) for applying the short-circuit mode to an output phase having the smallest absolute value of a phase voltage, and switches the first drive signals to the second drive signals. This allows for providing the current source power conversion apparatus that is able to suppress the frequency change of the current ripple while reducing the amplitude of the common mode voltage. |
