Technical Field
The invention relates to the technical field of electronic speed regulators, in particular to an electronic speed regulator integrating capacitor temperature control, a temperature control method thereof and an unmanned aerial vehicle.
Background
Inside the electronic governor used by the drone are also various electronic components, among which the electrolytic capacitive element, due to its construction and to the technical conditions, can withstand a maximum temperature of 105 ℃. The closer to this temperature, the lower the operating efficiency of the capacitor, and above this temperature the capacitor is very vulnerable.
Other high-power heating elements, such as MOS tubes, inside the electronic governor generate a large amount of heat, but the MOS tubes themselves can withstand about 250 degrees Celsius. When the radiating fins of the electrically-adjustable shell are in a high-temperature state during working, the electrolytic capacitor generates little heat, but the electrolytic capacitor is easy to be in a low-efficiency working interval or even damaged because the temperature of the shell is too high because the electrolytic capacitor is attached to the shell. The service life of the capacitor is halved when the working environment temperature of the aluminum electrolytic capacitor rises by 10 ℃, so the temperature control of the capacitor is important for prolonging the service life and improving the reliability.
The electrolytic capacitor may not be attached to the housing, for example, exposed outside, so that the electrolytic capacitor is easily damaged by high temperature and high humidity of the external environment or foreign matters when working on the aircraft.
