The power management circuit includes: a first power extraction circuit including a rectification circuit converting AC power at a first input unit into DC power; a second power extraction circuit including a switching circuit operating with power from the storage and generating DC power using AC power at a second input unit; and a switch circuit having a first connection mode of connecting the first input unit to the generation units to receive an AC voltage greater in effective value than an AC voltage to the second input unit, and a second connection mode of connecting the second input unit to the generation units to receive an AC voltage greater in effective value than an AC voltage to the first input unit.",
