Bidirectional DC-DC converter |
摘要 |
A bidirectional DC-DC converter includes a series circuit of a first winding of a first reactor, a second reactor, and a first switch connected to both ends of a first DC power source, a series circuit of a second switch and a second DC power source connected to both ends of the first switch, a series circuit of a second winding of the first reactor, a third reactor, a first selector switch, and a first diode connected to both ends of a series circuit of the second reactor and the first switch, a series circuit of a second selector switch, a second diode, and the second DC power source connected to both ends of a series circuit of the first selector switch and first diode, and a controller turning on/off the switches and the selector switches. |

1. A bidirectional DC-DC converter stepping up a DC voltage of a first DC power source for supplying the stepped-up voltage to a second DC power source, and also, stepping down a DC voltage of the second DC power source for supplying the stepped-down voltage to the first DC power source, the bidirectional DC-DC converter comprising:
a first reactor that includes first and second windings connected in series and electromagnetically coupled with each other; a first series circuit that includes the first winding of the first reactor, a second reactor, and a first switch and is connected to both ends of the first DC power source; a second series circuit that includes a second switch and the second DC power source and is connected to both ends of the first switch; a third series circuit that includes the second winding of the first reactor, a third reactor, a first selector switch, and a first diode and is connected to both ends of a series circuit of the second reactor and first switch, an anode of the first diode being grounded; a fourth series circuit that includes a second selector switch, a second diode, and the second DC power source and is connected to both ends of a series circuit of the first selector switch and first diode; and a controller turning on/off the first switch, second switch, first selector switch, and second selector switch for carrying out step-up and step-down operations between the first and second DC power sources. |
