HVDC models
Description:
These models contain a 3-phase rectifier (AC/DC) and a 3-phase inverter (DC/AC).
The average model (AM) just contains a control circuit that is connected to several controlled sources.

DC component suppressor
Description:
This model suppresses the DC component in the measure of a fault current to keep only the permanent part.
AC and DC components meter
Description:
This example contains a device which calculates the DC and AC components.
- The DC component is available in the DC control scope with half
a cycle delay versus the simulation time
- ... see moreThe AC component is available in the DC control scope with one
cycle delay versus the simulation time
Once the maximum DC magnitude is reached, the time constant is
determined assuming the DC decay is exponential and uninterrupted

Zero-crossing fault
Description:
This example provides a device which is a 3-phase bolted fault.
Once the simulation time has passed faultTime, the first phase voltage
crossing zero triggers the fault on the 3 phases simult... see moreaneously.
