Circuit coupling: principles


The numerical analysis of electrical devices can be restricted by the complexity of the power supply. It may be difficult to get the values of the supplying voltages and/or currents of the different electrical circuits of the device.

By introducing the electrical equations directly into the software of magnetic field computation, the field - circuit coupling allows the treating of electrical conductors and of their supply circuit.

Utilization example

The field - circuit coupling allows, for example, the simulation of:

  • a D.C. electrical machine with commutator and the supplying circuit of the machine winding
  • a variable reluctance electrical machine whose coils are supplied by a chopper
  • a transformer with the primary winding connected to a supplying network and the secondary winding connected to a load circuit
