升压装置
摘要：
即使在被配置为检测电抗器电流的电流传感器56出现“卡住”故障期间，也要执行正确的控制。通过升压转换器12的升压电压、以及所述电流传感器56检测到的位于所述升压转换器12中的电抗器54的电抗器电流的反馈控制来控制升压转换器12。当所述电抗器电流的变化小于预定电流值时，执行所述电流传感器的故障判定，如果升压前电压的变化超过预定电压值，则判定所述电流传感器的故障。
摘要（英）：

Proper control is performed even during a stuck abnormality of a current sensor 56 configured to detect a reactor current. A boosting converter 12 is controlled by feedback control of a boosted voltage of the boosting converter 12 and a reactor current, detected by the current sensor 56, of a reactor 54 in the boosting converter 12. When a variation of the reactor current is less than a predetermined current value, failure determination of the current sensor is performed and, if a variation of the pre-boosting voltage exceeds a predetermined voltage value, failure of the current sensor is determined.
