【Abstract】 The bidirectional DC/DC converter used to connect the DC microgrids with different voltages can help to realize the bidirectional energy flow between the DC microgrids,which is conducive to the absorption and utilization of the internal energy of the DC microgrids.The working principle of bidirectional DC/DC converter used to connect DC microgrids with different voltage is analyzed,and a new strategy of improved PI control is proposed.The stability of the control strategy is also analyzed through small signal modeling,and the effectiveness of the control strategy is verified by PLECS simulation.更多还原
