This thesis develops a supercapacitor Reflex charger with digital control. The supercapacitor module is charged by a Li-ion battery using a synchronous buck converter. With the consideration of supercapacitor characteristics and operation voltage conditions, four charging modes are integrated, including the incremental charging method, the constant current charging method, the Reflex charging method and the constant voltage charging method. Secondly, Integrating the maximum duty cycle limitation, average current control, and bidirectional mode to achieve the improved Reflex charging method. In addition, protection of Li-ion batteries and supercapacitors is added into the system to ensure safe operation. Finally, both the PSIM simulation and the experimental results are used to verify the theoretical correctness and feasibility.
