1. They have inductors and are not stiff.
2. They have voltages and have zero impedance.
If the branches are stiff or are purely resistive with or without a voltage, their currents will need to be calculated by nodal analysis. The code to set the branch currents is:
The actual nodal analysis is:
Other than that, the code is quite the same as the previous case. This code was tested with a three phase diode bridge rectifier and was found to be working OK. The previously released code was breaking.
