The Discrete Library

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

The Phasors Library

The Phasors library contains the phasor versions of some of the continuous models described above. See the Tutorial chapter for more details on the phasor simulation.

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 you 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.
