3页在 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.为了设置的圈数比为不同的值(例如 230 至 12 匝比)更改 F1 和 F2 为 1 / n 的值(1/19.167 = 0.052; 230 至 12 圈数比,其中 N =初级/次级)另请注意,您必须设置 E1和 E2 至 F / 2(0.052 / 2 = 0.026 圈数比)。
变压器知识:输入 220AV,输出 22AV 则变比 n = 220/22 = 10;例:输入是 230AV,我想输出为 12AV,则 n = 230/12 = 19.16;在 MULTISIM 仿真中修改变压器参数 F1 = F2 =1/19.16=0.052 而 E1=E2=0.052/2 = 0.026;multisim 中各种变压器都是什么意思?例如 SUBCKT ts_pwr_10_to_1 1 2 3 4 5 //.SUBCKT 是子电路命令此子电路名为 “ts_pwr_10_to_1 ”;有 5 个引脚* *1, 2-- primary winding, *3,4-- secondary terminal, 5-- neutural //注释行1,2 为主绕组;3,4 为副绕组终端;5 为中间抽头Rs1 1 11 1.000e-3 //Rs1 为 1 11 端之电阻,值为 1/1000 欧Rl2 31 3 1.000e-3 //R12 为 31 1 端之电阻,值为 1/1000 欧Rl3 41 4 1.000e-3 //R13 为 41 1 端之电阻,值为 1/1000 欧。
