PROBLEM TO BE SOLVED: To simultaneously secure an engine starting performance and the stability of a power voltage in operating under load in a battery-less power supply device. SOLUTION: A power generated in an AC generator 11 is supplied to a power line L through a regulator 12. A fuel injection system (F1 load) 13 and a first capacitor 14 are connected parallel with the power line L. Also, a DC load 15 and a second capacitor 16 are connected parallel with the power line L through a switch 17. After charging to the first capacitor 14 is completed, charging to a second capacitor 16 is performed by turning on/off the switch 17. When a plurality of loads included in the DC load 15 are simultaneously operated, power is additionally supplied from the second capacitor 16 to the DC loads 15 to prevent the voltage of the power line L from lowering.
