multisim中变压器的设置.doc

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。L1 11 2 5.000e+000 /L1为 11 2端之电感量，值为1亨。L2 31 5 5.000e-002 /L1为 31 5端之电感量，值为0.05亨。L3 5 41 5.000e-002 /L1为 5 41端之电感量，值为0.05亨。K12 L1 L2 9.999e-001 /K12 为L1和 L2之间的耦合系数，值为0.9999。注：0K1K13 L1 L3 9.999e-001 /K13 为L1和 L3之间的耦合系数，值为0.9999。K23 L2 L3 9.999e-001 /K12 为L2和 L3之间的耦合系数，值为0.9999。.ENDS /子电路结束。= Model template =这些可以按以下步骤找到：1.
