    Abstract: Introduction was made to a kind of bi-directional active voltage equalization system for super-capacitor stacks with the flyback converter technology. The system with a microcontroller as the core collected monomer voltage of super-Capacitor stacks in real time, drove the bi-directional flyback converter according to the monomer voltage, and transferred energy in bi-direction between monomer super-capacitor and adjacent super-capacitor stacks to realize bi-directional active voltage equalization. The experiment results show that the system is able to equalize super-capacitor stacks more effectively and bi-directional energy transfer efficiency is above 80%.
    Key words: super-capacitor stack; bi-directional active equalization; flyback converter; energy transfer efficiency
