A power conversion apparatus includes AC power supplies, If an abnormality occurs in any one of the AC power supplies and loads that are respectively connected to two capacitors are not balanced, voltages of the two capacitors are balanced. When an abnormality occurs in a first or second AC power supply, a first reactor is connected to a second reactor in series, a battery supplies energy to the two capacitors, and a current flowing to the first reactor is controlled by a first switch. In this manner, a voltage between the two capacitors is controlled.
