POWER CONVERSION CONTROL APPARATUS

摘要

The power conversion control apparatus is for controlling a power conversion circuit in which a plurality of pairs each including a high-side switching element and a low-side switching element connected in series to each other are connected in parallel to a capacitor, and an external battery is connected to the capacitor through a relay. To discharge the capacitor, the power conversion control apparatus turns on both the high-side and low-side switching elements of at least one of the pairs to make a short circuit between both electrodes of the capacitor on condition that the relay is open.
