<p>The power converter (50) includes a first operation mode in which each of switching elements (S 1 to S4) is controlled on or off independently so as to perform a power conversion between a load (30) and both a first DC power source (10) and a second DC power source (20) and a second operation mode in which every two of the switching elements (S 1 to S4) are controlled on or off concurrently so as to perform the power conversion between the load (30) and the first DC power source (10) or the second DC power source (20). A switching speed at which when each of the switching elements (S 1 to S4) is turned on or turned off is controlled in accordance with the operation mode. Specifically, the switching speed in the second operation mode is higher than the switching speed in the first operation mode.</p> |
