Discretizing the model might speed up the execution of the model. Starting with SimPowerSystems 4.1(R14SP2+), the "PowerGUI" block under the SimPowerSystems library can be used to discretize any model.
In previous releases of the product, for a model that has individual forced-commutated power components (GTOs, MOSFETs, IGBTs), discretization of the model is not possible. However, the "Universal Bridge" blocks can be discretized to be used in a discrete time step simulation. You can use the "Universal Bridge" block to model the individual forced-commutated power components (GTOs, MOSFETs, IGBTs). Once you have replaced the forced-commutated power components (GTOs, MOSFETs, IGBTs) with the "Universal Bridge" block, you can use the "PowerGUI" block to discretize the model. The following documentation page discusses simulation of discretized SimPowerSystem models.
The following documentation page provides details about the "Universal Bridge" block:
