摘要: When a control means turns on a pre-charging contactor, an AC current from an AC power source is converted into a DC current by a switching circuit to charge a smoothing capacitor. However, the smoothing capacitor cannot be charged completely due to the operation of a capacitor of an LC filter. Therefore, when the voltage of the smoothing capacitor detected by a voltage detecting means exceeds a predetermined value, the smoothing capacitor is further charged by bringing the switching circuit into a boosting operation. Thus, even if an LC relay required in the prior art for invalidating the capacitor of the LC filter is not provided, it is possible to completely charge the smoothing capacitor, thereby providing a decrease in the number of parts and an enhancement in reliability of the pre-charging circuit, and preventing a reduction in performance of the LC filter due to a loss in the LC relay.
摘要翻译: 当控制装置接通预充电接触器时,来自交流电源的AC电流通过开关电路转换成直流电流,以对平滑电容器充电。 然而,由于LC滤波器的电容器的操作,平滑电容器不能完全充电。 因此,当由电压检测装置检测到的平滑电容器的电压超过预定值时,通过使开关电路进行升压操作,平滑电容器进一步充电。 因此,即使不提供现有技术中使LC滤波器的电容器无效化的LC继电器,也可以对平滑电容器进行完全充电,从而减少零件数量,提高可靠性 预充电电路,并且防止由于LC继电器的损失导致的LC滤波器的性能降低。
