用于将电能馈送到供电系统的变换器
摘要：
介绍了一种用于将电能馈送到供电系统(2)的变换器(3)，其具有：在各种情况下分别用于连接到DC电压发生器(1)的正负输出(4，5)的一个输入(6，7)；用于连接到供电系统(2)的两个输出(8，9)；装置，其具有存储电感器(L1)和开关(S1-S6)，用于将DC电压转换为AC电压。可被连接到DC电压发生器(1)的负输出(5)的输入(7)可被接地，两个输出(8，9)中的至少一个具有干线电感器(L2)。根据本发明，装置包含：具有两个电流路径(S4，L1，S6；S5，L1，S3)的桥式电路，其中的一个提供正输出电流，另一个提供负输出电流；用于以供电频率在两个电流路径(S4，L1，S6；S5，L1，S3)之间进行切换的开关单元；耦合电容器(1)，其将桥式电路连接到开关单元。
摘要（英）：

An inverter (3) is described for feeding electrical energy into a power supply system (2) having in each case one input (6, 7) which is intended for connection to the negative and positive output (4, 5), respectively of a DC voltage generator (1) two outputs (8, 9), which are intended for connection to the power supply system (2), and a device, which has a storage inductor (L1) and switches (S1 to S6), for conversion of a DC voltage to an AC voltage. The input (7) which can be connected to the negative output (5) of the DC voltage generator (1) can be grounded, and at least one of the two outputs (8, 9) is provided with a mains inductor (L2). According to the invention, the device contains a bridge circuit with two current paths (S4, L1, S6; S5, L1, S3) of which the one provides positive and the other negative output currents, a switching unit for switching, which is carried out at the power supply frequency, between the two current paths (S4, L1, S6; S5, L1, S3) and a coupling capacitor (1) which connects the bridge circuit to the switching unit.
