Universal Bridge

– 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.
