Abstract
In an electric power conversion system having a discharge control device capable of discharging a voltage charged in a capacitor to a voltage of not more than a predetermined voltage, a linear regulator decreases a voltage of the capacitor and outputs the decreased voltage to a drive unit at a bottom arm in a U phase. A flyback converter for discharging use inputs an output of the linear regulator, and outputs electric power to a drive unit at an upper arm in the U phase. When detecting that own vehicle collides with an obstacle, the discharge control device starts to execute discharge control of the capacitor by turning off a photo coupler and turning on the linear regulator.
