Abstract :
An equalization management system based on buck-boost converters is proposed. This system uses pulse width modulation (PWM) signal to control the voltage balance between adjacent cells in super-capacitor modules connected in series, which can effectively balance cells´ voltage during the charge-discharge process, and avoid the weak cells from being overcharged or over discharged. Thus enhance the profitability of limited capacitance.
