【Abstract】 This paper presented a method for each single supercapacitor to be used as a voltage equalizer component,solving the problem of different charging rate due to different factors such as monomer capacity and initial voltage. For the problem of unstable DC output voltage,the Boost circuit with PI regulation is used to realize stable output of DC voltage. For the problem of alternating voltage,through AT89 C51 microcontroller with the singlephase full bridge inverter circuit to realize stable output of AC voltage,making a visualization of the energy contained through A/D conversion module. Finally,the effectiveness of the circuit was verified by PSIM and Proteus simulation software.更多还原
