Electromagnetic Converter

Lossless electromagnetic energy conversion device

Magnetic Elements

Description

The Electromagnetic Converter block provides a generic interface between the electrical and magnetic domains.

The block is based on the following equations:

where

Magnetomotive force (mmf) across the magnetic ports
ΦFlux through the magnetic ports
ICurrent through the electrical ports
VVoltage across the electrical ports
NNumber of electrical winding turns
tSimulation time

Connections N and S are magnetic conserving ports, and connections + and – are electrical conserving ports. If the current from the electrical + to – ports is positive, then the resulting mmf is positive acting across the magnetic N to S ports. A positive rate of change of flux flowing from N to S results in a negative induced voltage across the + and – ports.

Basic Assumptions and Limitations

Electromagnetic energy conversion is lossless.
