+# # Q3D Dynamic link to Twin Builder for the DC-Link bus bars of a drive inverter
+#
+# This example demonstrates how to link an existing Q3D Extractor Design of the inverter DC-Link bus bars
+# with a frequency sweep to a Twin Builder design using Q3D Dynamic Component - State Space link.
+# This will integrate the broadband parasitic model of the bus bars into the Twin Builder schematic.
