Description

The Electromagnetic Converter unit provides an interface between electrical and magnetic networks.

The block is based on the following equations:

,

,

Where:

  • - is the magnetomotive force (MDF) at the magnetic ports.

  • - flux through the magnetic ports.

  • - current through the electrical ports.

  • - voltage across the electrical ports.

  • - number of winding turns.

  • - modelling time.

Connections N and S are magnetic ports, and connections + and - are electrical ports. If a positive electric current flows from port + to port - , the resulting MDS is positive, acting through the magnetic ports N to S. The positive rate of change of flux flowing from N to S results in a negative induced potential difference at ports + and - .

Key assumptions and limitations

Electromagnetic energy conversion is lossless.
