Abstract

The invention discloses a super capacitor multi-mode quick charge circuit design method, which comprises the following steps: 1) selecting resistance of a resistor RS; 2) enabling one end of the resistor RS to be connected with the cathode output end of a Buck convertor circuit, and enabling the other end of the resistor RS to be grounded; 3) selecting elements having appropriate parameters and forming a charging mode control circuit; 4) connecting the elements to form the charging mode control circuit; 5) selecting elements having appropriate parameters and forming a charging drive circuit; 6) connecting the elements to form the charging drive circuit; and 7) connecting the Buck convertor circuit, a voltage source, a super capacitor and the charging drive circuit to form a super capacitor multi-mode quick charge circuit. The method is simple in steps, reasonable in design, convenient to realize, high in practicality and convenient for popularization use.

Description

technical field [0001] The invention belongs to the technical field of supercapacitor charging circuits, and in particular relates to a design method of a supercapacitor multi-mode fast charging circuit. Background technique [0002] With the development of society and economy, people pay more and more attention to green energy and ecological environment. As a new type of energy storage device, supercapacitors are getting more and more attention because of their irreplaceable advantages. Supercapacitors have many advantages such as large storage energy, fast charging speed, long cycle life, high power density, good ultra-low temperature characteristics, and environmental protection. Compared with batteries, it has the advantages of lower series equivalent resistance, longer service life, wider temperature operating range, wider voltage variation range, maintenance-free and sealable. At present, there are mainly the following charging methods for supercapacitors, constant cu...
