Lossless electromagnetic energy conversion device
The Electromagnetic Converter block provides a generic interface between the electrical and magnetic domains.
The block is based on the following equations:
|MMF||Magnetomotive force (mmf) across the magnetic ports|
|Φ||Flux through the magnetic ports|
|I||Current through the electrical ports|
|V||Voltage across the electrical ports|
|N||Number of electrical winding turns|
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.
To set the priority and initial target values for the block variables prior to simulation, use the Initial Targets section in the block dialog box or Property Inspector. For more information, see Set Priority and Initial Target for Block Variables.
Nominal values provide a way to specify the expected magnitude of a variable in a model. Using system scaling based on nominal values increases the simulation robustness. Nominal values can come from different sources, one of which is the Nominal Values section in the block dialog box or Property Inspector. For more information, see Modify Nominal Values for a Block Variable.
