Abstract:
A power conversion device includes: a DC/DC convertor (5) that performs DC/DC conversion on an output voltage of a direct-current power supply (for example, a solar battery module (1)); and a DC/AC invertor (6) that performs DC/AC conversion on an output voltage of the DC/DC convertor (5). The output power of the DC/AC invertor (6) is controlled such that the charge and discharge of a storage device (for example, a storage battery (3)) connected to a connection point between an output end of the DC/DC convertor (5) and an input end of the DC/AC invertor (6) are controlled.
