传统变压器的寄生电容可以用作谐振式DC-DC变换器的谐振元件，以减小整个系统的尺寸。为了在不建立变压器的情况下预测寄生电容的值，比较了计算寄生电容的不同方法。系统地总结了已知的方法，并补充了不同理论和缺失方程之间的缺失环节。在此基础上，提出了一种新的简单的寄生电容建模方法。通过对四种不同高压互感器的测量验证了所得方程。
Parasitic capacitances of conventional transformers can be used as resonant elements in resonant DC-DC converters in order to reduce the overall system size. For predicting the values of the parasitic capacitors without building the transformer different approaches for calculating these capacitances are compared. A systematic summary of the known approaches is given and missing links between the different theories and missing equations are added. Furthermore, a new simple procedure for modelling parasitic capacitances which is based on the known approaches is proposed. The resulting equations are verified by measurements on four different high voltage transformers.
