随着更薄的金属和更浅的外壳要求的出现，对射频（RF）感应操作的需求正在增加。虽然感应加热的理论基础对所有频率都是相同的，但射频的电源及其操作却有很大不同。本文探讨了这些差异，并提供了如何为各种应用正确选择射频设备的信息。

The need for radio frequency (RF) induction operations are increasing as thinner metals and shallower case requirements occur. While the theoretic basis of induction heating is the same for all frequencies, the power supplies and their operations are considerably different for RF. This paper explores those differences, and provides information on how to properly select RF equipment for various applications.
