Abstract
When a control device of an electric automobile carries out fixing control for fixing the energization or cut-off of semiconductor switches 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 the power systems. When only the first cut-off control is implemented, the energization or the cut-off of the semiconductor switches 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 and semiconductor switches}.
