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, acting through the magnetic ports N to S. The positive rate of change of the flow 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.

Ports
