开腔二极管的功率损耗和修正的Child Langmuir定律

Power loss in open cavity diodes and a modified Child Langmuir Law

Debabrata Biswas, Raghwendra Kumar, R. R. Puri

摘要:

大多数高功率器件中使用的二极管本质上是开路的。它示出,在这种情况下,有一个电磁辐射的损失,导致较低的临界电流相比,封闭的二极管。功率损耗可以通过引入有效势而纳入标准Child-Langmuir框架中。修正的Child-Langmuir定律可用于预测给定板间距和电势差的最大功率损耗以及该功率损耗的最大传输电流。理论的有效性进行了数值测试。

英文摘要:

Diodes used in most high power devices are inherently open. It is shown that under such circumstances, there is a loss of electromagnetic radiation leading to a lower critical current as compared to closed diodes. The power loss can be incorporated in the standard Child-Langmuir framework by introducing an effective potential. The modified Child-Langmuir law can be used to predict the maximum power loss for a given plate separation and potential difference as well as the maximum transmitted current for this power loss. The effectiveness of the theory is tested numerically.
