Description

Block Electromagnetic Converter provides an interface between electrical and magnetic networks.

The block is based on the following equations:



where

  • — magnetomotive force (MDS) on magnetic ports;

  • — flow through magnetic ports;

  • — current through electrical ports;

  • — voltage on the electrical ports;

  • — the number of turns of the winding;

  • — simulation time.

The N and S connections are magnetic ports, and the * and *−* connections are electrical. If a positive electric current flows from port * to port −, then the resulting MDS is positive and acts through the magnetic ports N to S. The positive derivative of the magnetic flux flowing from N to S leads to a negative induced potential difference at the ports + and −.

Key assumptions and limitations

The conversion of electromagnetic energy occurs without loss.
