摘要：

Compact, isolated DC-DC converters are required in many applications such as communication terminals. This paper presents a compact, planar Class E-2 DC-DC converter via wireless inductive coupling. For high frequency converters working at megahertz (MHz), it is challenging to design the system parameters under the condition of different final loads and voltage ratios. In this paper, a design method is proposed to adjust the voltage ratio of a Class E-2 DC-DC converter without changing the turn ratio of the coils. An experimental 6.78 MHz Class E2 converter system with flexible voltage ratio is built, with the coupling coefficient k=0.33 and overall efficiency above 80%.
