中压电网电源馈电的输入滤波器预充电
摘要：
提供了一种预充电装置，所述预充电装置包括配置成向电容器供应预充电电压的变压器和配置成耦合到变压器并对增大的调制指数做出响应的变换器。在电容器变得基本充满之后的时间量子之内调制指数增大，且在所述时间量子期间预充电电压基本恒定。
摘要（英）：

A device includes a transformer configured to supply a pre-charge voltage to a capacitor and a converter configured for coupling to the transformer and responsive to an increasing modulation index. The modulation index increases for a time quanta after the capacitor becomes substantially fully charged and the pre-charge voltage is substantially constant during the time quanta.
