<p>PROBLEM TO BE SOLVED: To provide a power supply apparatus which can increase a DC output when a machine is in low speed operation, suppress the output when the machine is in high speed operation and reduce the DC output when the machine is accelerated to improve acceleration. SOLUTION: The one end of a capacitor 3 is connected to the positive side DC output terminal T1 of a diode full-wave rectifier circuit 2 which rectifies the outputs of 3-phase generating coils U, V and W which are star-connected in a magnet generator 1. A capacitor 4 is connected between the other end of the capacitor 3 and the negative side DC output terminal T2 of the full-wave rectifier circuit. A switch 5 is connected between the connection point of the capacitors 3 and 4 and the neutral of the 3-phase generating coils U, V and W.</p> |
