Abstract

The invention relates to a three-port DC/DC converter for high-power charging and belongs to the technical field of automobile driving and control. The three-port DC/DC converter solves the problem that a traditional non-isolated buck topology cannot freely and simultaneously realize high-power charging and the control of the free charge-discharge requirements of a battery. An input capacitor is connected in parallel with a voltage source; the positive pole of the voltage source is connected to the drain of a switching transistor Q1; the source of the switching transistor Q1 is connected to the cathode of a diode D1; the anode of the diode D1 is connected to the negative pole of the voltage source; the source of a switching transistor Q2 is connected to the cathode of the diode D1; the drain of the switching transistor Q2 is connected to the cathode of a diode D2; the anode of the diode D2 is connected to the positive pole of a battery; the negative pole of the battery is connected tothe anode of the diode D1; one end of an inductor L1 is connected to the source of the switching transistor Q2; the other end of the inductor L1 is connected to the drain of a switching transistor Q3;the source of the switching transistor Q3 is connected to the anode of a diode D3; the cathode of the diode D3 is connected to the positive pole of the battery; one end of an output capacitor is connected to the drain of the switching transistor Q3; and the other end of the output capacitor is connected to the negative pole of the battery. The three-port DC/DC converter is suitable for automobiledriving and control.
