The control method of the bi-directional DC-DC converter in charging and discharging process of supercapacitor was proposed in this paper, which was applicable to the vast majority of the supercapacitor charging and discharging occasions. Charging and discharging circuit model of supercapacitor was constructed in the PSCAD/EMTDC power system simulation software. By analyzing the non-compensation bi-directional control model, PI or PID controller was used in the bi-directional DC-DC system to realize the stability of the system. In order to reduce the charging current pulsation, the multiple charges to the supercapa:citor were introduced, and also the simulating results were presented. The stable simulating system and the excellent simulation results verify the method is feasible.
