9、计算铁心截面积Sc公式如下：

计算得出Sc＝6.3平方厘米

漏感比1000-2000即可，看管子不同要求不同

8、计算变压器漏感La计算公式为：

借助一个例子大家来一起讨论一下单端输出牛的设计

高保真输出变压器要求初级开路电感L1与漏感La之比大于10000。根据上述公式计算得出La《＝0.00538H

7、计算初级绕组电感量L1输出变压器设计要求的初级绕组电感量L1设计要求的公式如下：（当然越大越好）

（推挽机）其中：fL为最低工作频率（单位：Hz），在这里我取30Hz，一般不需要太低，否则制造成本太高。          M为失真系数，

；一般取在下限频率，响度为1dB时。根据上述公式，本例为单端机，计算得出L1>=53.08H
