Abstract
A power conversion unit includes an input end to connect with a DC power supply, a first DC voltage end configured of a first terminal and a second terminal, a second DC voltage end configured of a third terminal and a fourth terminal, a converter, and a controller that controls the converter. The converter performs DC/DC conversion accompanied by power transmission between the input end and the first and second DC voltage ends. The controller generates a control command for the converter controlling a first voltage at the first DC voltage end and a second voltage at the second DC voltage end to a voltage target value.
Claims15
A power conversion unit comprising:
- an input end to connect with a DC power supply;
- a first DC voltage end configured of a first terminal and a second terminal;
- a second DC voltage end configured of a third terminal and a fourth terminal;
- a converter to perform DC/DC power conversion accompanied by power transmission between the input end, and the first DC voltage end and the second DC voltage end;
- and
- a controller to control the converter,
- the controller generating a control command for the converter controlling a first voltage at the first DC voltage end and a second voltage at the second DC voltage end to a voltage target value, wherein
- the controller
- operates the converter by selecting one of a first mode in which the first voltage and the second voltage are controlled accompanied by power transmission between the input end, and the first DC voltage end and the second DC voltage end and a second mode in which the first voltage and the second voltage are controlled accompanied by power transmission between the first DC voltage end and the second DC voltage end, based on a state of a power supply from the DC power supply through the input end.
