Abstract :
The RF-DC differences (δ) of thermal converters are calculated from complex transmission line theory. The Boella effect and the skin effect are considered. The formula δ=Af1/2 +Bf2 can be obtained by experiments and proved by comparison of converters. The uncertainty of δ is 0.01% at 1 MHz and 0.1% at 30 MHz
