Functionality
Switching function modeled with extensional logical node VSWI represents the switch-
controlled voltage triplet as:
GUID-27479273-EAED-40B8-BD13-DD29D8B12610-ANSI V1 EN
Figure 419: Representation of switch-controlled voltage triplet
VSWI performs the switching function between two voltage groups (Bus 1 and Bus 2).
Residual voltage input can be optional and it depends on the HV configuration. The
switching operation can also be performed on the residual voltage.
