<p>PROBLEM TO BE SOLVED: To enable effectively lessening of torque required for the rotation of a rotor of a generator when supplying to a load such as a secondary battery, generated power of the generator having the rotor which is rotated by a manually rotated drive mechanism. SOLUTION: This power supply device is provided with a three-phase AC generator having a stator and a rotor, a manual rotating section 12 which rotates the rotor of the three-phase AC generator 11 to let the three-phase AC generator 11 generate power and a speed-increasing section 13, and voltage.current converting means 42, 44 which are connected between the output terminal of the three-phase AC generator and a secondary battery 45 or a capacitor 46 for storing power and which supply generated power of the three- phase AC generator 11 to the secondary battery 45 or the capacitor 46, for storing power under the condition that the output voltage of the three-phase AC generator 11 be relatively large and the output current of the three-phase AC generator be relatively small.</p> |
