Universal Bridge - Implement universal power converter with selectable topologies and power electronic devicesLibrary 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. 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). The Universal Bridge block is the basic block for building two-level voltage-sourced converters (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: For the case of a two-phase diode or thyristor bridge, and for any other bridge configuration, the order of commutation is the following: GTO-Diode bridge: 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). Snubber resistance Rs The snubber resistance, in ohms (Ω ). Set the Snubber resistance Rs parameter to inf to eliminate the snubbers from the model. Snubber capacitance Cs The snubber capacitance, in farads (F). Set the Snubber capacitance Cs parameter to 0 to eliminate the snubbers, or to inf to get a resistive snubber. In order to avoid numerical...
