The super capacitor charging device comprises an input control switch unit, an EMI processing unit, a signal collection unit, a driving unit, a control and protection unit, a single-phase input rectification unit, a current feed topology unit and an output switch control unit which are electrically connected. The device charges a super capacitor by adopting a current feed topology structure and voltage mode control and feed-forward compensation control technologies, and can realize a mode of two-section charging for the super capacitor, thereby realizing wide input, high efficiency, low cost, reliable performance and strong applicability of the charging device, and greatly promoting the process of industrialization of the super capacitor. The device provided by the invention is applied to charging of super capacitor banks with wide AC voltage input.

Description

technical field [0001] The present invention is a device for charging a super capacitor. By using the device to charge the super capacitor group, a two-stage charging mode for the super capacitor can be realized. The device is suitable for charging a supercapacitor bank with a wide AC voltage input. Background technique [0002] The power source of pure electric vehicles is battery, which is affected by the characteristics of the battery itself, and the battery has weak shock resistance. As a kind of electric double layer capacitor, supercapacitor has high power density and efficiency due to special raw materials and production methods. , has the dual characteristics of battery and capacitor, and has become a power source with excellent performance. Supercapacitors meet the market demand for power sources with high frequency, high strength, high cycle times, and comply with environmental protection policies, and have excellent development prospects in the fields of electric...
