Zusammenfassung:	A current-source power converting apparatus (100 to 102) in an embodiment includes a current-reference generating unit (31), a polarity determining unit (32), a PWM-pulse-signal generating unit (33), and a drive-signal generating unit (34). The current-reference generating unit (31) outputs a phase current reference and a line-to-line current reference. The polarity determining unit (32) determines a polarity of the phase current reference. The PWM-pulse-signal generating unit (33) generates a PWM pulse signal by comparing the line-to-line current reference and a carrier signal. The drive-signal generating unit (34) generates a drive signal that drives each of a plurality of switching elements, based on the PWM pulse signal and a polarity of the phase current reference.
