Zusammenfassung: | The utility model relates to the technical field of electronic circuits, in particular to a series super capacitor quick charging circuit, which comprises a boost DC/DC (direct current/direct current) driving module and a super capacitor bank, the boost DC/DC driving module comprises a driving chip, an inductor and a diode; wherein the power supply input end of the driving chip is connected with a direct-current power supply, the driving end of the driving chip is connected with one end of the inductor and the anode of the diode, and the voltage feedback end of the driving chip detects the voltage of the super capacitor bank through the voltage division circuit; the current feedback end of the driving chip detects the current-limiting voltage formed on the current detection resistor by the charging current of the super capacitor bank through the current detection resistor; the other end of the inductor is connected with the DC power supply. The cathode of the diode is connected with the super capacitor group |
