Problems solved by technology
In the prior art, the weak point of civilian drones is the battery power problem. Generally, the flight time is very short, and the battery performance degrades seriously after a period of use, and the battery life is short. However, the existing drone battery charger The unstable charging of the drone will also cause some damage to the drone battery, which will reduce the battery life of the drone. Therefore, there is room for improvement

The invention discloses a constant-current charger for an unmanned aerial vehicle battery, which comprises a first resistor, a second resistor, a third resistor, a first capacitor, a second capacitor,a first triode, a second triode, a rectifier, a silicon controlled rectifier and a potentiometer, wherein the third resistor, the silicon controlled rectifier and the potentiometer form a continuously adjustable constant voltage source to provide reference voltage for a base electrode of the second triode, the voltage stabilization value of the circuit is continuously adjustable, and the voltagestabilization value determines the maximum output voltage of a voltage-stabilized power supply. If the adjustable voltage range needs to be expanded, the resistance values of the third resistor and the potentiometer can be changed, so that the current and the voltage can be constant. The unmanned aerial vehicle battery is stably charged through the rectification and constant-current design, and the voltage output precision is high. The constant-current charger has a function of continuously adjustable voltage output, enables the service life of the unmanned aerial vehicle battery to be prolonged, and has popularization and application values.
Description
technical field [0001] The invention relates to the technical field of drones, in particular to a constant current charger for batteries of drones. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle" ("UAV"), is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned Paraplane etc. In the prior art, the weak point of civilian drones is the battery power problem. Generally, the flight time is very short, and the battery performance degrades seriously after a period of use, and the battery life is short. However, the existing drone battery charger The unstable charging of the drone will also cause some damage to the drone ...
