<p>PROBLEM TO BE SOLVED: To increase amount of power generation while stability of rotation of an engine is kept within the low rotation range. SOLUTION: An engine rotation number discriminator 48 detects the number of rotations of a rotor. When the number of rotations of engine is in the lower rotation field, a driver 46 controls a rectifier 4 with the power feeding of the delayed angle to increase a field magnetic flux and also increase the amount of power generation. The driver 46 reads the amount of delayed angle stored in a delayed angle setting unit 49, in response to polarity change of the poles detected with a rotor angle sensor 29, and feeds the power in the delayed angle to a stator winding. An output voltage of the power generator is controlled to be converged to a value between a voltage control value VMax and VMin which are lower than a regulation voltage of the regulator.</p> |
