Universal BridgeImplement 采用universal power converter 通用电源转换器with selectable topologies 可选拓扑and power electronic devices电力电子器件LibraryPower ElectronicsDescriptionThe Universal Bridge block 通用桥接模块implements实现 a universal three-phase power converter三相电源转换器 that consists of up to多达 six power switches connected in a bridge configuration六个以桥接方式连接的电源开关组成. The type of power switch and converter configuration are selectable from the dialog box电源开关和转换器配置的类型可以从对话框中选择.The Universal Bridge block allows simulation of converters using both naturally commutated自然换向 (or line-commutated线性换向) power electronic devices (diodes or thyristors二极管或晶闸管) and forced-commutated devices 强制换向器件(GTO, IGBT, MOSFET).The Universal Bridge block is the basic block for building two-level voltage-sourced converters (VSC)两级电压源转换器（VSC）.The device numbering is different if the power electronic devices are naturally commutated or forced-commutated. For a naturally commutated three-phase converter (diode and thyristor), numbering follows the natural order of commutation: 如果电力电子设备自然地换向或强制换向，则设备编号是不同的。 对于自然换向的三相变换器（二极管和晶闸管），编号遵循换向的自然顺序：For the case of a two-phase diode or thyristor bridge, and for any other bridge configuration, the order of commutation is the following:对于二相二极管或晶闸管桥的情况，以及对于任何其他的桥配置，换向顺序如下：GTO-Diode bridge:IGBT-Diode bridge:MOSFET-Diode and Ideal Switch bridges: Dialog Box and Parameters对话框和参数Number of bridge arms桥臂的数量Set to 1 or 2 to get a single-phase converter (two or four switching devices). Set to 3 to get a three-phase converter connected in Graetz bridge configuration (six switching devices).设置为1或2获得一个单相转换器（两个或四个开关设备）。设置为3以获得以Graetz桥配置（六个开关设备）连接的三相转换器Snubber resistance Rs缓冲电阻RsThe snubber resistance, in ohms . Set the Snubber resistance Rs parameter to inf to eliminate the snubbers from the model. 缓冲电阻，单位为欧姆。将缓冲电阻Rs参数设置为inf，以消除模型中的缓冲器。Snubber capacitance Cs吸收电容CsThe snubber capacitance, in farads (F). Set the Snubber capacitance Cs parameter to 0 to eliminate the snubbers, or to inf to ge
