POWER CONVERSION APPARATUS |
| 摘要 |
A power conversion apparatus is provided which includes a first DC/DC converter and a second DC/DC converter which are connected to each other in parallel, and a controller which changes a state of the second DC/DC converter between operation and stop, based on an input current or an output current of the power conversion apparatus, and at least one current threshold determined based on a first characteristic curve showing a relation between current and conversion efficiency in a state where the second DC/DC converter is stopped while the first DC/DC converter is operated and a second characteristic curve showing a relation between current and conversion efficiency in a state where the first DC/DC converter and the second DC/DC converter are operated. |

1. A power conversion apparatus, comprising:
a first DC/DC converter and a second DC/DC converter which are connected to each other in parallel; and a controller which changes a state of the second DC/DC converter between operation and stop, based on an input current or an output current of the power conversion apparatus, and at least one current threshold determined based on a first characteristic curve showing a relation between current and conversion efficiency in a state where the second DC/DC converter is stopped while the first DC/DC converter is operated and a second characteristic curve showing a relation between current and conversion efficiency in a state where the first DC/DC converter and the second DC/DC converter are operated. |
