功率/数据电耦合器、数据和电源传输网络
摘要：
功率/数据电耦合器、数据和电源传输网络。功率/数据电耦合器包括：发送变压器，由用于接收数据信号的绕组和连接在一起的两个绕组构成，两个绕组具有公共点和两个端子，两个端子旨在连接到总线的第一对线；接收变压器，由两个绕组以及用于传送数据信号的绕组构成，两个绕组具有公共点和两个端子，两个端子旨在连接到总线的第二对线。该功率/数据电耦合器还包括电流隔离变压器，具有：第一绕组，该第一绕组的端子连接到耦合器的电源引脚接触件；以及第二绕组和第三绕组，第二绕组和第三绕组的公共点连接到机械接地，并且第二绕组和第三绕组的各自由端子连接到发送变压器的绕组的公共端子，以及连接到接收变压器的绕组的公共端子。
摘要（英）：

An electrical coupler includes: a sending transformer having a winding for receiving data signals and two windings connected in series with a common point and two terminals to be connected to a first wires pair of a bus to deliver the data signals at the first winding terminals to said wire pair; a receiving transformer having two windings connected in series with a common point and two terminals to be connected to a second pair of wires of said bus to receive data signals on the pair of wires and a winding for delivering said data signals; and a galvanic isolation transformer with a first winding, the terminals of which are connected to the coupler's power supply pins, and second and third windings connected in series with a common point connected to a mechanical ground and the respective free terminals connected to the common terminals of sending and receiving transformers.
