之前我也是这种情况， 在百度和谷歌上各种论坛中询问最后得到了如何设置参数的方法。
这个方法是自己一步一步做出来的，希望对你有用。
第一步：打开软件。
第二步：器件选择如下
(以前我们学的知识是电压比等于线圈匝数比U1:U2=N1:N2)但是在multisim仿真中利用其提供的理想模型就可以了。
第三步：创建文件并绘制一个测试变压器的原理图(我们的目标是把交流220v 变成一个交流18v 的电路)。
第四步：参数设置如图途中要的是220v(AC)到18v(AC)，在Vale标签下，前面的原副默认为100mh先不变，最后一栏中的电感系数=18/220=0.0818≈0.082.点击OK.
测试电路数据基本上就是我们的220V到18V.
我来回答吧 也遇到过这个问题 找到答案了

在Multisim中创建一个230/12V的变压器
To create a 230 to 12 volt transformer, please follow the instructions
below:
1. Start up Multisim.
2. Enter the Basic Bin and click on the Linear Transformer button
(Transformer with the center tap).
3. In the Browser - Basic window, click on the TS_IDEAL Transformer Model.
4. Click on the Edit button at the bottom of the window.
5. Click Ok on the Database Select - To window (should be set at User).
6. In the Component Properties window, click on the Model Tab and under the
Model Data window, you will find the following:
.SUBCKT ts_audio_10_to_1 1 2 3 4 5
* EWB Version 4 - Transformer Model
* n= 10 Le= 1e-006 Lm= 0.001 Rp= 1e-006 Rs= 1e-006
Rp 1 6 1e-006ohm
Rs1 10 3 1e-006ohm
Rs2 11 5 5e-007ohm
Le 6 7 1e-006H
Lm 7 2 0.001H
E1 9 8 7 2 0.026
E2 8 4 7 2 0.026
V1 9 10 DC 0V
V2 8 11 DC 0V
F1 7 2 V1 0.052
F2 7 2 V2 0.052
.ENDS
In order to set the Turn Ratio to a different value (eg 230 to 12 turn
ratio), change the F1 and F2 value for 1/n (1/19.167=0.052; 230 to 12 turn ratio
where n=primary/secondary). Also note that you must set E1 and E2 to F/2
(0.052/2=0.026 turn ratio).
7. Set the desired turn ratio.
8. Click on the Save/Exit button at the bottom of the window.
9. In the previous window, click on the Cancel button.
10. Select Refresh Component Toolbars under the View menu.
11. Enable the User Database and under the Basic Bin, you will find your Transformer Model.
放置一个虚拟变压器 在参数 的primary-to-secondary turns ratio 中输入 X 就是
。。。。。。。。。。。。。输入/X=输出
注意要用交流电源 而交流电源的 参数中的 voltage（PK）是峰值不是有效值
