STORAGE-BATTERY CHARGING DEVICE FOR A MOTOR VEHICLE, METHOD FOR OPERATING AN ON-BOARD STORAGE-BATTERY CHARGING DEVICE, HIGH-VOLTAGE VEHICLE ELECTRICAL SYSTEM AND USE OF A STORAGE-BATTERY CHARGING DEVICE

摘要

A storage-battery charging device for a motor vehicle is configured to be arranged in the motor vehicle. The device includes a first stage with a power correction filter, and a second stage with an inverter. The first stage is electrically connected to the second stage by way of an intermediate node, the intermediate node being directly electrically connected to a feed-in connection point for direct voltage. The feed-in connection point is designed for direct electrical coupling to a high-voltage vehicle electrical system of the motor vehicle.
