Abstract
A capacitor connected to the battery in parallel; a step-up converter connected to the battery and the first capacitor; another capacitor connected to the step-up converter in parallel; an inverter connected to the step-up converter and the other capacitor in parallel; a potential line connecting a negative-side terminal of the battery to the capacitor, the step-up converter, the other capacitor, and the inverter in the stated order; and a bypass path formed, when a lower arm switching device of the step-up converter has a short-circuit failure, from cutting the reference electric potential line at a position including at least any one of a position between the negative-side terminal and the capacitor and another position between the step-up converter and the other capacitor. The bypass path bypasses the lower arm switching device and connects the negative-side terminal to the inverter.
