Abstract: |
In order to meet the demand of power conversion system with the increasing scale of high-power energy storage system, the interleaved DC/DC converter is used in the topology of high power conversion system. It is found that the interleaved DC/DC converter has a significant advantage in the current ripple and harmonic by analyzing the characteristic of the DC/DC converter. The droop control is added to the control strategy of the power conversion system. The simulation model and experimental prototype about the topology and control strategy of power conversion system are built. The results demonstrate the proposed converter has large power charge/discharge function with good performance. |
