Power System Blockset

The Discrete Library

The Discrete library contains the discrete version of the continuous models described above.

The Switch Current Source Library

This library contains models of power electronic devices, which are simulated by a current source external to the linear circuit. These devices are the diode and the thyristor with Lon>0, and the three forced commutated devices: Gate-turn-off thyristor (GTO), metal-oxide-semiconductor-field effect transistor (MOSFET), and the insulated-gate-bipolar transistor (IGBT). All these models are continuous and contain an internal inductance, allowing to handle fast transitions of forced commutated converters. As for electrical machines, these models use a voltage input (output of the state-space model of the linear circuit) and their current output is fed into the state-space model. All these models are vectorized.
