摘要:
A first switch (21) connects a series circuit (16) made up of a coil (15) and a third capacitor (13) between a high-voltage terminal (17a) and the intermediate-voltage terminal (17b). A second switch (22) connects the series circuit (16) between an intermediate-voltage terminal (17b) and a low-voltage terminal (17c). A third switch (23) connects the series circuit (16) with a power supply (90). A controller (24) switches a mode among the following three modes. In a first mode, the first switch (21) is closed, and the second switch (22) and the third switch (23) are open. In a second mode, the second switch (22) is closed, and the first switch (21) and the third switch (23) are open. In a third mode, the third switch (23) is closed, and the first switch (21) and the second switch (22) are open. The controller (24) controls the switches (21, 22, 23) such that the mode is repeated in order of the third mode, the first mode, the third mode, and the second mode.
