<p>PROBLEM TO BE SOLVED: To provide a small and light actuated generator which can output AC and DC and operates so that it is held to a prescribed output voltage, even if output voltage differs. SOLUTION: A change-over switch 5, which changes over a system to an independent connection state where the output of DC voltage rectified from first main coils 1 and 2 through diodes 22 and 24 can be fed to a load and a series connection state where the first mail coils 1 and 2, a second main coil 3 and a pickup coil 11 are connected in series and the output of AC voltage can be fed to the load, is provided. A variable resistor 12 dividing voltage induced in the pickup coil 11, so that an output voltage can be varied when it is used in the independent connection state and a resistor 13 dividing voltage induced by the pickup coil 11 to a connection point, to which one end of the second main coil 3 and one end of the pickup coil 11 are connected, when it is used in the series connection state are installed. The change-over switch 5 selectively connects the variable resistor 12 and the resistor 13 to an automatic voltage adjusting unit 9. Exciting current supplied to a field coil 10 is controlled, and output voltage is held to a prescribed voltage.</p> |
