Of course, the generator must have a regulating mechanism to ensure electrical output and medical certification. But as soon as you step on the accelerator, the voltage soars and the car circuit is instantly paralyzed.
How to regulate power generation?

The answer is to adjust the magnetic field strength of the generator. As mentioned in junior high school physics, generators generate electricity by cutting magnetic induction lines by coils. The faster the cutting speed (rotation speed), the higher the magnetic field strength and the higher the voltage. We can't adjust the speed, we can only adjust the magnetic field strength. When the output voltage of the generator is low, the voltage regulator will energize the excitation coil and increase the magnetic field strength to increase the output voltage. When the output voltage is too low, the voltage regulator will energize the excitation coil and increase the magnetic field strength to increase the output voltage. When the output voltage is too low.
