Non-Ideal Common Mode Inductor

In addition to common mode inductance, the Non-Ideal Common Mode Inductor model provides for leakage inductance, inter-winding capacitance, and winding resistance.

Leakage inductance is specified by entering a value for leakage inductance or by entering a coupling factor.  A coupling factor of 1 equates to 100% coupling; 0.99 equates to 99% coupling, etc.

The Non-Ideal Common Mode Inductor is a magnetically coupled four-terminal component.  The number of turns is equal, upper and lower, so the voltage across the upper windings is equal to the voltage across the lower windings.  Impedance across the inductor windings varies over frequency.

The Non-Ideal Common Mode Inductor is available for series schematic diagram components.  Since the Non-Ideal Common Mode Inductor is a four-terminal component it occupies two series component positions simultaneously.  If another component already exists in either series component position it will be replaced by the Non-Ideal Common Mode Inductor.

To calculate and graph the impedance of the Non-Ideal Common Mode Inductor component over the frequency range selected on the Frequency Range form, click the Graph button on the Component Library form toolbar or select menu Tools | Graph.

To change a Non-Ideal Common Mode Inductor value, select the present value, enter the desired value, and click the OK button.  When the OK button is clicked the Non-Ideal Common Mode Inductor is placed on the schematic diagram.  If the Close button is clicked the Component Library form closes with no changes to the schematic diagram.
