Aerial vehicle, and overvoltage protection method and device of electronic governor in the same

An overvoltage protection device for an electronic governor in an aerial vehicle, wherein the electronic governor is configured to control a motor, and the device comprises:

• a memory comprising computer-executable instructions stored thereon, and
• a processor, which is configured by the instructions to implement acts of:
• collecting a direct current (DC) bus voltage of the electronic governor,
• when the DC bus voltage is greater than a first voltage threshold and less than or equal to a second voltage threshold, adjusting a control parameter of the electronic governor based on a difference between the DC bus voltage and the first voltage threshold, such that the electronic governor controls the motor based on the adjusted control parameter to restrain a further rise of the DC bus voltage, wherein the second voltage threshold is greater than the first voltage threshold.
