This example demonstrates coupling a quasi stationary circuit with a DC circuit. The QS voltage is rectified (using an ideal AC DC converter), loaded by a variable load conductor. The conversionFactor = DC voltage / AC rms voltage in this case is the root mean square of a rectified sine, i.e., 1. You may compare the quasi stationary results with that of a fully transient model (using a Graetz rectifier), plotting:
It can be seen that at the DC side the current is represented by its averaged value, at the AC side by its rms value.
The quasi stationary model needs a grounding at the QS side as well as the DC side, whereas the transient model may have only one ground since AC side and DC side are connected via the diodes.
