When a control device (50) of an electric automobile (10) carries out fixing control for fixing the energization or cut-off of semiconductor switches (24a, 24b) in each of at least one switching cycle, at least one cut-off control is implemented among a first cut-off control for cutting off both a power generation path and a power charging path of one power system, and a second cut-off control for cutting off all of the power generation paths or the power charging paths of all of the power systems. When only the first cut-off control is implemented, the energization or the cut-off of the semiconductor switches (24a, 24b) is controlled so that the number of power systems implementing the first cut-off control is N-1 {N being an integer of at least 2 representing the number of power supplies (22a, 22b) and semiconductor switches (24a, 24b)}. |
