PROBLEM TO BE SOLVED: To provide a power converter capable of reducing volume and power conversion loss while ensuring a function to output low harmonic AC voltage and current.SOLUTION: In the power converter, a DC positive terminal of a DC power supply 20 is connected to a switching element 11; and a DC negative terminal of the DC power supply 20 is connected to a switching element 14. A capacitor 18 and a capacitor 19 which are connected in series to each other are connected to the DC power supply 20 in parallel. A DC neutral point between the capacitor 18 and the capacitor 19 is connected to the switching element 12 and the switching element 13. The switching element 12 is connected to a positive terminal of a chopper cell group circuit 15; the switching element 13 is connected to a negative terminal of the chopper cell group circuit 16; and a negative terminal of the chopper cell group circuit 15 is connected to a positive terminal of the chopper cell group circuit 16; and the same is the output AC terminal. |
