Essential Electrical Modeling Techniques
Apply Simscape™ modeling rules when you build electronic, mechatronic, and electrical power system networks using Simscape Electrical™.
Three-Phase Ports
Connect three-phase blocks using composite ports for three-phase lines or expanded ports for single-phase lines.
Switch Between Physical Signal and Electrical Ports
Switch between a physical signal port and an electrical conserving port on a Simscape Electrical block.
