PROBLEM TO BE SOLVED: To provide a power buffer apparatus having a compact power storage section, enhancing the power efficiency and inexpensively achieved. SOLUTION: Single-phase inverters 31, 41 are sequentially connected to an output line U of a three-phase inverter 5A in series. Single-phase inverters 32, 42 are sequentially connected to an output line V in series. Single-phase inverters 33, 43 are sequentially connected to an output line W in series. A power storage unit 4 is connected to a DC section of the three-phase inverter 5A. Power storage units 7 are individually connected to DC sections of the single-phase inverters 31-33, 41-43.
