The overall program design of three-port DC-DC converter controlling the power flow was presented. The principle on the phase shift control managing the power flow between the ports was investigated, and a program using a PWM duty cycle to control the power flow circulation throughout the system to ensure the minimal loss of the entire system was proposed. Furthermore, a DSP-based control strategy with the decoupled power flow management was proposed to obtain fast dynamic response on small-signal dynamic analysis. Finally, the entire control model was built,and all the theoretical considerations were validated through simulation and experimental model. This research can improve capacity utilization and work efficiency, thus achieving the purpose of the rational use of energy in mix power flow management system of hybrid electric vehicles and distributed power generation.
