理想变压器输出端与输入端视在功率相等的条件

The Condition of Equal Visual Power for Output and Input in Ideal Transformer

本文利用基尔霍夫定律,通过严格推导,得出具有两个以上副线圈的理想变压器中输出端与输入端视在功率相等的条件.

In this paper,with rigorous calculation by employing the Kirchhoff's law,we have al-ready obtained a condition that inputvisual power is equal to output visual power in the idealtransformer which contains more than two secondary coils.
