PURPOSE: A multi-stage generator is provided to change excessive input energy into electricity even when input energy excessively increased. CONSTITUTION: A multi-stage generator comprises a switch control part(460). The switch control part contains a switch controller, a magnetization switch and a demagnetization switch. The switch controller receives a control signal from the central control part and controls each switch connected to individual generator. The magnetization switch is connected between the rotor for a field magnet of individual generator and the external voltage source of the magnetization switch. |
