PROBLEM TO BE SOLVED: To simplify the configuration of a power source device to selectively supply with commercial power source or solar cell output.SOLUTION: The power source device includes: an input determination section that determines which of a commercial power source and a generated power source is input as the input power to generate a determination signal; a switching type conversion unit that converts the input voltage into an output voltage; and a drive signal generation section which receives the determined output supplied from the input determination section to generate a switching drive signal for the conversion unit. When the power source device determines that the commercial power source is input based on the determination signal, the drive signal generation section generates a switching drive signal as a power factor improve control unit. When the power source device determines that the generated power source is input based on the determination signal, the drive signal generation section generates a switching drive signal as a maximum power point follow-up control unit. |
