摘要：High frequency power electronic technology is an important development tendency for future power supplies. ON-OFF control is widely adopted in high frequency applications up to multi-megahertz. A detailed analysis of the high frequency Class E dc-dc converter with ON-OFF control over wide input voltage range is performed in this paper. It is revealed that with the increase of input voltage, the soft switching realization become easier and the output power capacity is enhanced; concurrently, the voltage/current stresses of the power components are all increases. Based on this, design considerations of the Class E dc-dc converter with wide input voltage range are given. It is pointed out that, to help achieve soft switching and rated output power requirements over the whole input voltage range, the converters' parameters should be designed at the minimum input voltage; on the other hand, to avoid electrical damage of the power components, the voltage and current stresses of the components should be considered at the maximum input voltage. A design example of 20 MHz, 10 W Class E dc-dc converter are given with 918 V inputs. The experimental results are presented to verify the necessity and feasibility of the proposed design considerations. © 2018 IEEE.
