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.
