PROBLEM TO BE SOLVED: To achieve high efficiency utilization and constant voltage of power for all states of rated load, no-load, low speed rotation, and high speed rotation, without using a dummy resistor system, or a reactance drop system and a winding switching system, by setting the input voltage to a control circuit at a withstand voltage or less when the power generation voltage is large during no-load or during high rotation and high output.SOLUTION: A power generator 10 applies an output voltage to a load 12 and the output winding of the U-phase, V-phase and W-phase of a permanent magnet generator 20 has a number of turn of 1/2 so that the output voltage becomes 1/2 of a rated voltage, and consists of mutually parallel two systems of output windings U1 and U2, V1 and V2, W1 and W2. The output voltage in the output winding of two systems is stabilized for each system by step-down DC/DC converters 34-1, 34-2, after each system is rectified independently for U-phase, V-phase and W-phase in a control circuit 30, and that outputs are added in series by an adding and connecting section 38 before being applied to the load 12. |
