A power supply control device includes a control unit, and a power path that is connected to a primary external power system. If a connection state between the primary external power system and the power path is in a disconnected state, the control unit is configured to control power output of at least one power conditioner of at least one corresponding secondary external power generation unit, based on (a) an amount of power consumption of a specific load connected to the power supply control device through the power path, and (b) a power generation output of the secondary external power generation unit.

Power supply device, power supply system, and method of controlling power supply

A power supply device includes: an input determination section configured to determine which one of a commercial power supply and a power generator is an input power supply, and to generate a determination signal; a conversion section of a switching type configured to convert an input voltage into an output voltage; and a drive-signal generation section configured to be supplied with determination output from the input determination section, and to generate a switching drive signal for the conversion section, the drive-signal generation section being configured to serve as a power-factor correction control section and to generate the switching drive signal when the determination signal indicates that the commercial power supply is the input power supply, and being configured to serve as a maximum power point tracking control section and to generate the switching drive signal when the determination signal indicates that the power generator is the input power supply.
