Abstract:
1. A power converting apparatus including a DC-DC converter circuit configured to step up or down input voltage from a DC power supply and a DC-AC converter circuit configured to convert output voltage of the DC-DC converter circuit into AC, the power converting apparatus comprising: a first control circuit configured to control the output voltage; and a second control circuit configured to control an input current of the DC-DC converter circuit, wherein: the first control circuit generates a target current value which is a target value of the input current such that the output voltage becomes a voltage target value which is a target value of the output voltage; the second control circuit controls the DC-DC converter circuit such that the input current becomes the target current value generated by the first control circuit; and the first control circuit is provided with a ripple removing circuit configured to remove a ripple component included in the output voltage.
