Universal Bridge - Implement universal power converter with selectable topologies and power electronic devices 通用电桥-具有可选择的拓扑结构和电力电子设备的通用电源转换器的实现 Library Power Electronics Description The Universal Bridge block implements a universal three-phase power converter that consists of up to six power switches connected in a bridge configuration. The type of power switch and converter configuration are selectable from the dialog box. 通用电桥模块可以看作一个通用的三相电源转换器，由最高六个电源开关连接在一个桥路中配置。电源开关和转换器配置类型参数在对话框中选择。 The Universal Bridge block allows simulation of converters using both naturally commutated (or line-commutated) power electronic devices (diodes or thyristors) and forced-commutated devices (GTO, IGBT, MOSFET). 通用电桥模块可以仿真自然换流器（或换线）电力电子器件（二极管或晶闸管）和强迫换流器件（GTO、IGBT，MOSFET）。 The Universal Bridge block is the basic block for building two-level voltage-sourced converters (VSC). 通用电桥模块是建立两级电压源变换器的基本块（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: 不同自然换流或强迫换流电力电子器件的编号是不同的。一个自然整流三相转换器（二极管或晶闸管），编号：按下列顺序： For the case of a two-phase diode or thyristor bridge, and for any other bridge configuration, the order of commutation is the following: 两相二极管或晶闸管桥的情况下，和任何其他的桥配置，换向顺序如下： GTO-Diode bridge:GTO-二极管电桥 IGBT-Diode bridge: MOSFET-Diode and Ideal Switch bridges: Dialog Box and Parameters Number of bridge arms 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，得到一个单相转换器（两个或四个开关器件）。设置为3，得到一个连接在格雷茨电桥中的三相转换器（六开关设备）。 Snubber resistance Rs The snubber resistance, in ohms (Ω). Set the Snubber resistance Rs parameter to inf to eliminate the snubbers from the model. 缓冲电阻，欧姆（Ω）。设置缓冲电阻的参数为inf 来消除来自模型的缓冲。 Snubber capacitance Cs The snubber capacitance, in farads (F). Set
