<P>PROBLEM TO BE SOLVED: To provide a DC-AC power converter capable of stably supplying electric power from a DC power supply. <P>SOLUTION: The DC-AC power converter 100 includes: a DC power supply 1; a plurality of bidirectional switches; a DC reactor 2; output voltage command output means 11 that outputs an output voltage command VAC_REF; first PWM command generation means 14 that generates a PWM signal 1; second PWM command generation means 15 that generates a PWM signal 2; and switch distribution means 16 that distributes the PWM signal 1 and the PWM signal 2 to switch control signals for the corresponding predetermined bidirectional switches for outputting, based on a polarity discrimination signal SIGN of the output voltage command VAC_REF, within one cycle of the output voltage command VAC_REF. <P>COPYRIGHT: (C)2012,JPO&INPIT |
