| Abstract: | A generator voltage controller suitable for modern fuel vehicles is designed to achieve good control of generator voltage and reduce voltage fluctuation. The pulse width modulation method is used to control the generator excitation system. The current of excitation system is controlled by a power MOS transistor, and the pulse width is regulated by PID algorithms. Finally, the good control of generator voltage is verified by tests. |
