Setting Up an External Circuit Using the Maxwell Circuit Editor

Note: One use for an external circuit can be to supply an excitation to a coil terminal, rather than using a voltage type of excitation.

 

Note: External circuits intended for use with the Time Decomposition Method (TDM) can only support basic circuit elements that are solution-independent. This is because, for TDM, all time steps (or all time steps in a subdivision) are solved simultaneously - and thus the circuit topology and its parameters must be known before solving. Therefore some circuit elements, such as solution-dependent switches, diodes, capacitors, and inductors which are not directly connected to windings in series, are not supported.

The driving circuit for the winding in this design consists of a voltage source in series with a resistor and with the winding. When complete, the circuit should look similar to the following figure.

To set up the external circuit, follow this general procedure:

  1. Add the circuit elements.
  2. Connect the circuit elements in series.
  3. Export the netlist.
  4. Save the Maxwell Circuit Editor project.
  5. Assign the external circuit.
